轮轨关系中的等效锥度对车辆动力学性能的影响

The Influence of Equivalent Conicity in Wheel-rail Relationship on the Performance of Vehicle Dynamics

轮轨关系涉及到轨道车辆运行的稳定性和安全性,轮轨匹配问题越显的重要。作为轮轨匹配的最重要参数之一等效锥度,与车辆的动态横移量和滚动圆半径差存在着一定的关系,影响着车辆动力学性能。

The relationship between wheel and rail is involved in the operational stability and security of rail vehicles, so the matching problem between wheel and rail is more and more important. As one of the most important parameters, the equivalent conieity has a certain relations with the amount of vehicle dynamic sliding and Rolling radius difference, and affects the vehicle dynamics performance.
