摘要/Abstract

摘要： 为了研究车轮磨耗对高速列车动力学性能的影响，建立了车辆动力学和车轮磨耗耦合模型。考虑车辆通过一条由直线和曲线组成的典型线路工况，采用Non-elliptic模型计算轮轨接触斑上的车轮磨耗量，以累积车轮型面磨耗量及更新型面外形。采用Archard磨耗模型研究车轮面磨耗的分布与发展，以车轮踏面磨耗深度达到0.1mm为型面更新的条件进入下一个磨耗循环的计算。最后加载磨耗后的车轮型面，研究磨耗对车辆系统通过曲线线路时的动力学性能的影响。

Abstract: To study the effects of wheel wear on high-speed train dynamics performance, a multi-body system dynamics and vehicle wear wheel coupling model was established. The vehicles were considered through a typical line conditions consisting of straight lines and curves. Non-elliptic model was used to calculate the amounts of wear on the wheels, the amounts of wear of the wheel profile cumulations and then the profile shapes were updated. Using Archard wear model, wheel tread wear depth of 0.1mm was considered for profile update conditions, and then the next calculation cycle wear began. Finally, wear wheel profiles were loaded to study the effects of wear on the dynamics performance of the vehicle systems through the curves.

Key words: wheel wear, dynamics performance, Non-elliptic model, Archard model
