Based on the system engineering and the theory of coupled orbit dynamics, the dynamic simulation model of the truck mounted on Zhuan 8A bogie was established and the nonlinear characteristics of bogie structure were considered in detail. After the theoretical simulation results are verified by experiments, the motion stability and straight running stability of the traditional truck on the elastic track are simulated.
