Based on the rolling stocktrack coupling dynamic theory, the paper systematically analyzes and studies the effects of antihunting absorber, primary suspension stiffness, truck wheel base, taper of tread on critical speed and the effect of the parameters on gauge, rail, rail base, fastener stiffness and damp ness on train stability by using the dynamic simulation software TTISIM. It points out when the critical speed of rolling stock is calculated not only the structural parameter and model for the complete train shall be taken into consideration, but also the whole track model and structural parameter and whole process. It plays a significant role in the engineering issues for optimizing design of the railway rolling stock structure parameter, increasing or upgrading the movement stability of rolling stock, improving the existing line for speed increasing and constructing high (fast) speed railways etc.
