Content available remote Variable Friction Coefficient Research on the Base of Motorbike Discbrake Assembly
EN
This article presents the research of the motorcycle braking process in real road conditions. The theoretical considerations of braking mechanics, construction of braking systems and friction phenomena that take place during motorcycle braking are presented. New and original concepts of acceleration and brake fluid pressure measuring systems are also submitted. The built measuring system was installed on a motorcycle and applied to experimental studies in order to investigate the variable friction coefficient. This original measuring system allows for recording values of pressure changes in the hydraulic braking system, acceleration in three axes and the temperature of the brake disc all at the same time. The obtained data allowed the calculations of several characteristics, e. g. motorcycle speed, brake power, braking distance and variable friction coefficient. As a result of this research, a special measuring system was prepared and a series of characteristics showed an interesting reflection of complex physical phenomena which motorbikes are subjected to during braking time. Information about variable friction coefficient obtained from energy based methods can be useful in theoretical investigation of friction phenomena.

Celem badań było określenie dominujących typów uszkodzeń obręczy wybranego pojazdu szynowego, a także zmian materiałowych będących wynikiem zużycia obręczy koła i szyny. Powierzchnie obręczy poddano badaniom makroskopowym i profilografometrycznym, twardości sposobem Vickersa oraz mikroskopowym za pomocą mikroskopu świetlnego Zeiss Epiquant sprzężonego z kamerą CCD i skaningowego mikroskopu elektronowego Tescan Vega 5135 wraz z mikroanalizatorem rentgenowskim PGT Avalon. Sprawdzony również został skład chemiczny materiału obręczy za pomocą spektrometru jarzeniowego GDS 500A firmy LECO. Podstawową formą zużycia badanych obręczy kół, jakie zostało rozpoznane na podstawie badań makroskopowych, był shelling. Najwięcej efektów zużycia zaobserwowano na powierzchniach tocznych. Należy zaznaczyć, że rozwój shellingu był w początkowej fazie. Powstałe wykruszenia nie występowały na całym obwodzie, a ich wielkość była nieduża. Wynika to prawdopodobnie z tego, że tramwaje eksploatuje się na krótkich odcinkach w porównaniu z pociągami. Ponadto w niewielkich obszarach warstwy wierzchniej stwierdzono obecność tzw. białej warstwy, co pozwala przypuszczać, że lokalnie dochodziło do większego (niż dla shellingu) nagrzewania ślizgających się powierzchni tocznych kół. Był to jednak proces lokalny, niemający kluczowego znaczenia w ogólnym przebiegu zużywania. Obręcze kół ulegały silnemu odkształceniu plastycznemu w szczególności na wierzchołkach obrzeża i przy skosach zewnętrznych profilu tocznego. Silne zgnioty spowodowały zwiększenie twardości o blisko 70% w porównaniu z twardością materiału wyjściowego. W warstwie wierzchniej rozpoznano MnS. Wtrącenia te, występujące np. w mikrostrukturze wierzchołków obrzeży, inicjowały delaminację. Może to przyczyniać się do powstawania pęknięć i w rezultacie do zwiększonego zużywania obręczy.

The aim of presented research was evaluation of the main types of tram wheel wear of chosen rail vehicle and material changes which appear as a consequence of wheel and rail wear. Following tests was performed: macroscopic research, profile tests, Vickers hardness measurements, microscopic research with light microscope (Zeiss Epiquant with CCD), scanning electron microscope (Tescan Vega 5135) with X-ray microanalizer (PGT Avalon). The chemical composition was also checked with fluorescent spectrometer (LECO GDS 500A). The basic form of wear was shelling, which was detected by macroscopic research. The most damage surface was rolling surface. It has to be underline that the shelling was in early stage of growth. Created shells did not appear in the whole circumference of wheel and their size were relatively not huge. It is probably due to short distances characteristic for trams (in the comparison with trains). Moreover, in same regions of rolling surface, so called white layer was detected. It allows to state that sliding surfaces of wheel were (in a very small areas) heated in to higher temperature than it happens in case of shelling. Nonetheless, it was very local process, so it is rather not important in general wear of tested wheels. Tram wheels were highly deformed, particularly on the top of the edge of the wheel, and in the vicinity of outside angle of rolling profile. High deformation caused 70% hardness increase in comparison to the core material. In microstructure MnS was detected. Its presence in the surface layer of the top of the edge of the wheel caused delamination. It could help to crack initiation and, as a result, more intensive wear of tram wheels.

Anatomical structures are characterized by free surfaces, and most are in lobed and pseudo-spherical shapes. The aim of this article is to analyze selected procedures for accuracy assessment of the shape and dimensions of these structures using certified sphere and Ball Bar standards and to propose metrology parameters facilitating comparison of diagnostic devices. The spherical standard of various materials and Ball Bar standards with various distances between spheres centers can be a tool for evaluation of computed tomography metrology applications. Errors in geometry mapping can be identified on the basis of standardized control systems used in coordinate measuring techniques.

The article presents the validation research scheme of metrological model of coordinate measuring arm (CMA) using multifeature check. The scheme shows the comparison of the calibration results of the check using selected coordinate methods and criteria of validation. The comparison shows the insignificance of differences between the obtained results of both: metrological model of CMA and multi-position method. It evidently proves the correctness of the development of metrological model of CMA. The use of appropriate quality multifeature check also had a significant impact on the results. This check is now the most accurate measurement length check and its use for this validation process was the most suitable.

The paper presents a method for estimating the uncertainty of optical coordinate measurement based on the use of information about the geometry and the size of measured object as well as information about the measurement system, i.e. maximum permissible error (MPE) of the machine, selection of a sensor, and also the required measurement accuracy, the number of operators, measurement strategy and external conditions contained in the developed uncertainty database. Estimation of uncertainty is done with the use of uncertainties of measurements of basic geometry elements determined by methods available in the Laboratory of Coordinate Metrology at Cracow University of Technology (LCM CUT) (multi-position, comparative and developed in the LCM CUT method dedicated for non-contact measurements) and then with the use of them to determine the uncertainty of a given measured object. Research presented in this paper are aimed at developing a complete database containing all information needed to estimate the measurement uncertainty of various objects, even of a very complex geometry based on previously performed measurements.

This research studies the impact of certain factors on the consumption of ammonia and nitrogen in the established nitriding processes (classical, Floe and Nitreg) and the most recent - ZeroFlow nitriding process. Analyzed are the parameters that can be, to some degree, adjusted and optimized by the users. These include the temperature of the process, atmosphere potential, phase constitution, nitrogen concentration in the surface layer and its thickness, as well as the type of atmosphere (NH3, NH3 + dissociated NH3, and NH3 + N2). In conclusion, it is established that the lowest consumption and emission of the industrial gases is achieved in a process where a precise control over the kinetics of the layer growth is exercised and a unary atmosphere - ammonia - is employed.

Nowadays, high effective carbon, nitrogen and phosphorus removal based on activated sludge is the most popular method of dairy wastewater treatment. In activated sludge systems efficient nutrient compounds removal is determined by the quantity and quality of easily available forms of organic carbon. For both biological phosphorus removal and biological nitrogen removal to occur, an easily biodegradable carbon source must be present in the treating wastewater. The organic compounds used in the processes of denitrification and enhanced biological phosphorus removal (EBPR) usually are presented in treating wastewater, what is called an internal source of carbon. However, many industrial wastewater, including dairy wastewater, very often do not have sufficient amounts of carbon, in relation to the concentration of nitrate and phosphates, to ensure efficient both denitrification and biological dephosphatation processes. When biological nitrogen and phosphorus removal is limited by the availability of easily biodegradable forms of organic carbon a supplemental carbon source must be add to the wastewater, hence so-called external source of carbon should be applied to provide energy necessary for the nutrient removing bacteria to grow and perform their work. One of the most popular sources of organic carbon is acetic acid, which is one of the best available forms of carbon by denitrifying bacteria and those accumulating polyphosphates (PAO). Apart from acetic acid and acetates use is made of a number of the volatile fatty acids (VFA), including propionic acid, butyric acid, valeric acid, and such substrates as: glucose, methanol or ethanol. Since the use of chemical compounds in the form of technical products (e.g. acetic acid, citric acid) is generally expensive, cost-saving solutions are sought. According to literature data, wastewater with high COD/(N + P) ratio after acidogenic fermentation can be used as an external source of VFA in wastewater with low concentrations of easily available organic compounds treatment. The aim of this study was to determine the influence of the filtration process on the content of organic compounds (measured as COD) in relation to the concentration of nutrients (measured as the sum of TKN and TP) in process dairy wastewater, in terms of the possibility of effective VFA production. It was observed, that filtration process ensures improvement of the COD/(N + P) ratio only in wastewater from the selected sections of dairy production. The best result, if percentage increase of the COD/(N + P) ratio is considered, was obtained for the wastewater from butter production. Densification of wastewater from butter production resulted in 95% increase of the COD/(N + P) ratio without a significant increased nutrient concentration. Filtration process provided the highest COD/(N + P) ratio (219,18 mg O2/(mg N + mg P)) and reduced both nitrogen and phosphorus concentrations in the permeate from the apparatus room. The results obtained suggest, that acidogenic fermentation of wastewater from the apparatus room and butter production with high COD/(N + P) ratio can serve as an external source of VFA in biological wastewater treatment process of wastewater with low concentrations of easily available organic compounds, which ensures effective nitrogen and phosphorus removal.

Beer is the fifth most popular drink all over the world. Annual consumption reaches 23 L per capita. In Poland, the brewery industry has been the subject of intensive transformations in the last 20 years as a result of, most of all, an increase in beer consumption and brewery wastewater quantity increase are observed. Two main cycles may be distinguished in the beer production process: production of malt and production of beer. Wastewaters are generated at all production stages: soaking and transport of grain (malt house), spent grain anddraff (brewhouse), yeast washing and waste yeast pressing (fermentation house), and mainly from processes of production appliances, rooms and packages cleaning. Hence, the quantity of generated wastewaters is significantly affected by the washing technology of appliances and installations. The study presents the physicochemical characteristics of wastewaters originated from the brewery plant production departments. Wastewater samples were taken from two brewery plants (BP) 1 and 2. They produce lager type beer. The mean water consumption in the breweries in the study period reached 0.30 and 0.45 m3 hL-1 of produced beer respectively for BP1 and for BP2. Wastewaters originated from: brewhouse, the process of spinning (centrifuge), fermentation house (fermentation tanks, horizontal unitanksUT), storage facilities (with facilities for filtration, storage in the pressurized tanks BBT type) and racking house – BP1 and frommalt house, brewhouse, fermentation house and racking house at BP2. In addition, analyses were conducted on a mixture of wastewaters originating from the whole brewery plant that, apart from the above-mentioned production wastewaters, contained wastewaters from social facilities and administrative buildings.Physicochemical analysesincluded: pH, suspended solids, total nitrogen, total phosphorus, COD and BOD. Results of the study demonstrate a correlation between the site of wastewaters generation, specific character of a unitary technological process and the quality of wastewaters discharged to a sewage system, including their potential biodegradability. The highest average concentration of organic compounds (COD and BOD) (28161 mg O2 ∙ L-1 and 13595 mg O2 ∙ L-1) and total phosphorus (75,2 mg P ∙ L-1 )were observed in the effluents produced during the centrifuge process at the brew house. Wastewater from brewhouse located at BP1 characterized by the highest suspended solids concentration (924 mg d.m. L-1). The maximum values of total nitrogen (132,9 mg N ∙ L-1)were reported in the effluent from the fermentation process (BP2).Despite significant differences in the quality of wastewaters, they were characterized by the C:N:P ratio beneficial for the biological treatment, irrespective of the source of their origin.Ratios of BOD : (TKN + TP) (>25)in brewery wastewaters indicate the potential for highly-effective process of biological N and P removal. These ratios show that the processes of denitrification and biological phosphorus removal should not be limited by the availability of the organic substrate. Moreover, most examined brewery wastewater streams can be applied as external carbon source in biological processes removal of nitrogen and phosphorus from wastewater containing insufficient amounts of biodegradable organic matter.

Content available remote Udział grawimetrii w kartowaniu struktur geologicznych w Karpatach
PL
Metoda grawimetryczna jest skutecznym narzędziem do kartowania struktur geologicznych, m.in. w warunkach karpackich, często ograniczających możliwości prospekcyjne innych metod. Potwierdzają to rezultaty prac grawimetrycznych z okolic Żegociny, Tuchowa i Stępiny. W pierwszym rejonie, poprzez transformację anomalii w redukcji Bouguera, prześledzono zmiany litologii i tektoniki utworów przypowierzchniowych, uzyskując obraz grawimetryczny w dużym stopniu zbieżny z widocznymi na mapie geologicznej wydzieleniami i elementami tektoniki. W rejonie Tuchowa dane grawimetryczne przede wszystkim posłużyły do sporządzenia, na drodze modelowania rozkładu gęstości, przekroju geofizycznego, pozwalającego oszacować rozmieszczenie i głębokość interesujących geologów naftowych osadów węglanowych dewońskich i jurajsko-kredowych. W okolicach Stępiny interpretację grawimetryczną ukierunkowano głównie na wyznaczenie stromo nachylonych granic gęstości, wykorzystując odpowiednie metody przetwarzania wartości pomierzonego pola siły ciężkości. W rezultacie odwzorowano w przedziale 0÷4 km p.p.m. układ linii tektonicznych tożsamych generalnie z uskokami, nasunięciami, fleksurami czy też innymi granicami kompleksów o różnej gęstości. Podane przykłady, zdaniem autorów, potwierdzają celowość stosowania kartografii grawimetrycznej do kompleksowych analiz budowy strukturalnej.

The gravimetric method is an effective tool for the mapping of geological structures including the Carpathians area where other geophysical methods are limited in prospective possibilities. This is confirmed by results of gravity researches in the areas of Żegocina, Tuchów and Stępina. In the first region lithology and tectonic changes in near surface rocks were traceable through transformations of Bouguer anomaly. Thus, the gravimetric image was obtained, which is largely consistent with divisions and tectonic elements visible on the geological map. Gravimetric data from the Tuchów area were primarily used for preparing a geophysical cross-section by modeling of density. This made possible to estimate location and depth of the Devonian and Jurassic-Cretaceous carbonate sediments, which are especially important for petroleum geologists. In the Stępina area, the gravimetric interpretation was primarily directed to determine steeply sloping density boundaries using appropriate processing methods based on gravity field data. In results tectonic lines system range 0÷4 km BSL were mapped. This line system of tectonic faults is generally similar to, flexures and other boundaries with different densities. In the author’s opinion, examples presented confirm the usefulness of a gravimetric cartography for comprehensive analysis of geological structures.
