Assessment of the Impact of Wear and Tear of Rubber Elements in Tracked Mechanism on the Dynamic Loads of High-Speed Tracked Vehicles

Abstract The operation of high-speed tracked vehicles takes place in difficult terrain conditions. Hence, to obtain a high operational reliability, the design or modernisation process must be precise and should consider even slightest details. article presents issues related problem formulating vehicle models using partial flexible elements used mechanisms. Changes occurring shape properties such as track pads roadwheel bandages consequence operating conditions are presented. These changes reflected presented elastic–damping characteristics components crawler mechanism. Numerical studies have shown that deterioration chassis suspension after significant mileage may increase dynamic loads (forces) acting on running gear. Increased forces gear naturally result increased stresses road surface which is travelling, can pose danger (or excessive wear tear) infrastructure culverts, bridges viaducts. In literature, model tests objects carried out represent new vehicles, adopted correspond not affected by Its influence ignored design, testing special vehicle. mechanism, gear, designed for off-road driving. ensures traversability. originating from driving superimposed those generated engine, drive train interaction tracks with roadwheels, sprocket, idler supporting return rollers.
