Abstract

Analysis of loadings acting on auto-train under most probable and recurring operation conditions is performed in this work. The largest loading exerted both on empty autotrain with empty trailer and on the loaded one is the longitudinal inertia force that depends on trailer mass and longitudinal acceleration determined by longitudinal acceleration acting at its weight centre. With given longitudinal loading acting on the device body attached to empty and loaded trailers being subjected to time-varying acceleration, corresponding to experimental and theoretical results of research of acceleration dynamics, it was established that dynamic factor was observed just after driving acceleration had ceased acting – subsequent vibration of parts of the coupling device did not exceed extreme values obtained in the initial moment
