摘　　要：针对某出口重载机车的车轮进行强度校核,并对车轮辐板截面形状进行尺寸优化。考虑热-机械耦合情况下车轮在各工况下的应力分布,保证车轮质量增加不超过10 kg,辐板应力有大幅度降低,提出辐板优化的几何特征,为重载机车车轮辐板截面的合理设计与优化提供参考。The intensity check of the wheel and size optimization of the section shape for wheel web are carried out for the exported heavy haul locomotive.Considering the wheel stress distribution in the various operating conditions under the thermal-mechanical interaction,the geometric features of the wheel web optimization are proposed to ensure the wheel mass not exceeding 10 kg while the wheel web stress significant reduction.This will provide the references for the reasonable design and optimization of the wheel web section shape for the heavy haul locomotive.
