车轮踏面形状对动力学参数的影响分析及优化设计

Effect of wheel tread shape on dynamic parameters and optimization design

文章利用多体动力学软件SIMPACK,分析对比了LMA、LMB、LMC、LMD四种踏面分别与60 kg/m轨面匹配的动力学性能,并在此基础上设计研发了一种新型踏面LMX,并对其动力学性能进行了分析。结果表明,LMX型踏面具有良好的性能,其在保证直线性能的同时,曲线性能也大幅提升。

Using multibody dynamics software SIMPACK,the dynamic performances of four kinds of wheel tread,LMA,LMB,LMC and LMD,matching with 60 kg/m rail surface,are analyzed and compared.On this basis,a new type of wheel tread LMX is designed and developed,and its dynamic performance is analyzed.LMX wheel tread has good performance,ensuring the straight line performance and greatly improving the curve performance.
