OBRUM sp. z o.o. w swojej 50-letniej działalności w ramach przemysłowego potencjału obronnego zrealizował szereg nowoczesnych projektów wyrobów przeznaczonych dla wojsk inżynieryjnych. W artykule zostały przedstawione i przypomniane najważniejsze opracowane przez kadrę naukowo-techniczną wyroby Ośrodka zbudowane na podwoziach gąsienicowych. Jasno definiowane potrzeby i dobra współpraca z wojskami inżynieryjnymi przyniosły konkretne wdrożenia o nowoczesnych rozwiązaniach technicznych. Specjalizacja OBRUM sp. z o.o. w zakresie sprzętu inżynieryjnego wynikała z potrzeby wykorzystania dostępnych podwozi i unifikacji pojazdów produkowanych w kraju. W zrealizowanych wyrobach wykorzystane były podwozia czołgów T-54, T-55, T-72 i PT-91. Opracowano i wdrożono maszyny typu ciągnik, układacz min, wóz zabezpieczenia technicznego czy czołg inżynieryjny.

During the 50 years of OBRUM's functioning in the defence industry the company has completed a number of projects pertaining to modern products for the engineering troops. This article presents the major products based on tracked chassis developed by OBRUM's research and technical staff. Clearly defined needs and good cooperation with the engineering troops have brought about launching of products based on modern technological solutions. OBRUM's specialization in the field of engineering equipment resulted from the need to use the available chassis and to ensure compatibility between the vehicles manufactured in the country. In the products developed use was made of chassis of tanks T-54, T-55, T-72 and PT-91. The machines developed and introduced into production included tractors, minelaying vehicles, recovery vehicles and engineer tank.

In the paper there were described assumptions and methodology of building the mathematical model of the transmission system of tracked agricultural tractor. There was presented model including 34 mass elements jointed by elasto-damping elements. As a result of calculations were estimated parameters of those elements basing on measurements of real object as well as were formulated differential equations of movement taking into account the underslung working equipment. As well were described the method of modelling transmission components, especially taking into consideration reaction moments between elements transmitting power and the chassis of the tractor. There was presented the way of defining the course of engine torque and estimated the main harmonics, with ultimate influence on dynamic loads of transmission. In the range of examination of the transmission operating loads, model takes into account the inputting changes of clutch friction torque during switching it on and off. Model gives ability to analyze the dynamic loads of transmission system depending on clutch slide. Model also allows existing clearances, what gives the possibility of analysis of abrasive wear influence on functioning of the transmission. Model enables the simulation of turning mechanism brakes operation during manoeuvring movement of the tractor.
