AbstractA vehicle moving on a flexible structure likewise a bridge beam with sudden acceleration and deceleration velocity causes sliding in wheels. This impact effect designing of rail components, supports and substructure. In this study ten degree of freedom (DOF) train bogie is considered to analyse effect of sudden acceleration and deceleration impact in terms of train bogie dynamics. Therefore, the bridge beam is considered simple supported Euler-Bernoulli beam with uniform crosssection. The equation of motion vehicle bridge coupled system has been obtained Lagrange equation and these equations converted to first order state-space representation using state variables. Then equation of motion of entire system has been solved step by step technique using fourth order RungeKutta algorithm in time domain and results have been presented in the study in term of vehicle dynamics.
