摘要
在现场测量的货车车轮轮缘踏面廓形的基础上,利用数据分析的方法探讨了货车车轮踏面廓形及廓形参数的基本演变情况,并通过动力学仿真计算和线路运行试验,分析了车轮磨耗对货车运行性能的影响。
On the basis of the freight car wheel tread profile measured in field,the digital analysis method is used to discuss the basic evolution of the freight car wheel tread profile and parameters of the profile.Via dynamics simulation calculation and operation test on track,the effect of wheel wear on the operation performance of freight cars is analyzed.
