| Abstract: | In this article,the snake movement stability of the wagon with 30 t-axle-load-bogie was analysed by using the dynamics analysis software NUCARS and obtain the critical spead of empty and loaded prototype-plan vehicles.The results show that the critical speed is influenced by some factors such as rubbertrays' vertical and lateral location stiffness,the bogie circumgyrate resistance moment,the bogie's anti-diamond-distortion stiffness,the anti-cut-distortion stiffness and the tread equivalent slope. |
