At the Opole University of Technology the concept was developed and a prototype was built of a reconfigurable vehicle, which is called Chameleon. It is the result of a project, which goal is to design and construct a small-dimension vehicle with low weight (up to 50 kg), which design would facilitate implementation of selected transport tasks, and its design allow for change or replacement of selected components, leading to changes in driveability, traction and durability. It was expected to construct a vehicle by means of which ideas and design solutions can be tested that is dedicated for the greatest variety of small-size vehicles. The Chameleon vehicle has been tested both while driving on a levelled surface and off-road (on uneven grassy surface). Both, the electric and pneumatic drives were tested. Also, the interaction of these two engines in the hybrid powertrain was investigated.

W Politechnice Opolskiej opracowano koncepcję i zbudowano prototyp pojazdu rekonfigurowalnego o nazwie Kameleon. Jest to efekt projektu mającego na celu zaprojektowanie i wykonanie małogabarytowego pojazdu o małej masie (do 50 kg), którego konstrukcja umożliwiałaby realizację wybranych zadań transportowych, a konstrukcja pozwalała na szybką zmianę lub wymianę elementów składowych prowadząca do zmiany właściwości jezdnych, trakcyjnych i wytrzymałościowych. Spodziewano się wytworzyć pojazd za pomocą którego mogą być testowane pomysły i rozwiązania konstrukcyjne dla jak największej gamy małogabarytowych pojazdów. Pojazd Kameleon został przetestowany zarówno podczas jazdy po równej nawierzchni oraz podczas jazdy w terenie (nierówna nawierzchnia trawiasta). Testowano zarówno napęd elektryczny jak i napęd pneumatyczny oraz współdziałanie tych dwóch jednostek napędowych w układzie napędowym hybrydowym.

W artykule zawarto opis trójkołowego pojazdu zbudowanego w większości z części rowerowych i napędzanego silnikiem elektrycznym. Przedstawiona koncepcja stanowi oryginalne osiągnięcie – od projektu, poprzez dobór elementów konstrukcyjnych i sterowania, aż do wykonania pojazdu i przeprowadzenia testów użytkowych. Głównymi kryteriami stawianymi przed nowym pojazdem były: prostota obsługi, niezawodność, dostępność elementów oraz koszt materiałów. W pracy przedstawiono również uzyskane wyniki testów prototypu oraz nakreślono kierunki dalszych prac.

The article includes a description of the three-wheeled vehicle built mostly from bicycle parts and driven by a DC motor. The concept is a original achievement – beginning from the design through selection of components and control system, until to the vehicle prototype performance and testing. The main criteria for the new vehicle were: ease of use, high reliability, availability of components and material cost. The paper presents the tests results and directions for further work.

Road safety was and still is one of the real hazards for human society all over the world. In order to manage the problem of excessive road death toll at the both sides of Atlantic two independent initiatives were started in 1970 in the USA in the US Department of Transportation. The paper describes the genesis of intergovernmental European initiative named EEVC, its history, participants and scope of former and current scientific research related to improvements in vehicle design safety. The work was started from the careful analysis of accident statistics data including the severity of accident. The important feature of EEVC working groups is participation of car industry researchers enabling wide verification of scientific achievements. For specific items, it is also shown the practical profit based on knowledge coming from EEVC research. Most important items resolved by EEVC were in-depth study of multidirectional impact mechanics, development of anthropometric dummies, pedestrian safety, passive/active safety interaction, rear under run protection etc. The influence of change in vehicle design appears important for all road users the vulnerable persons including. The relation to other similar international initiatives was pointed together with the future direction of activity and relation to National and International (UN ECE and EC) legislative bodies. The Polish input to EEVC research was described since in 2002 Poland started its participation.

The paper describes the evaluation of the pedestrian kinematics after a collision with a Sport Utility Vehicle (SUV) with a high bumper. To meet the goal two approaches were chosen. First, the authors carried out the SUV to pedestrian strike simulation using the certified, finite element lower legform impactor. The impact procedure mirrored the car vs. pedestrian collision described in the current Regulation (EC) 78/2009. However, it has been earlier noticed that the overall pedestrian kinematics response may vastly differ if the lower legform impactor hits a car with a high bumper. To evaluate this, an ellipsoid, standing Hybrid III dummy model was also investigated. Subsequent tests of the dummy model, impacted by the high-bonnet vehicle, confirmed that the stand-alone subsystem test with impactors leads to inaccurate assessment of the actual, after impact, pedestrian kinematics.

The development of armoured vehicles in each country is determined by the military doctrine, economic situation and technological advances. The article presents the variety of taken into consideration requirements, layout and final solutions. The leading industrial countries spend billions of dollars on armoured vehicles. The competition between projectile and armour designers finally resulted in highly effective armours introduced in the inventory of a number of countries. This has given a great number of ways and means of armoured vehicles protection. At the same time, high precision weapons, operating night and day in all weather conditions and against various types of defence, pose a great danger to armoured vehicles. It is emphasised in the article that the all-round protection of modern armoured vehicles is achieved by their camouflage in visible thermal radar and other regions of the spectrum, as well as by armoured structure featuring metal and non- metal materials and even explosives. There are presented, step by step, methods how not to be encountered, not to be seen, not to be hit, not to be penetrated and finally not to be killed. Among other things, electromagnetic (UV, VIS, IR, TIR, radar), mechanical (acoustic, seismic) and other (magnetic, chemical, smell, smoke, dust, traces) signature management categories are analysed. Also some examples of armoured designs and highly effective armours are presented. The final part of the paper is dedicated to individual and collective protection of armoured vehicles’ crews against NBC weapons as important factors that increase the survivability chances.
