中文摘要：
对某35t轴重机车车轮辐板形状进行优化，在曲线及道岔通过工况时，优化后的车轮辐板最大等效应力小于优化前，并且通过轮辐板优化降低了车轮质量。提出大轴重机车车轮辐板优化后形状的主要特征，为同类型车轮辐板设计提供参考。
英文摘要：
The wheel plate shape of 35 t axle load locomotive had been optimized. The maximum equivalent stress ot optimized ptate is less than the old one when the locomotive passing through a turnout and curve and the mass of optimized wheel was also reduced. The main features of wheel plate on heavy axial load locomotive had been proposed, which is a good reference for design the same type of wheel plate.
