摘要
采用Kalker CONTACT方法计算轮轨接触几何特性,分析对比了LM,LM_A,S1002CN,LM_(B-10),LM_D,XP55车轮踏面与TB 60,60D,60N钢轨廓型匹配的接触几何关系。分析结果表明:相同车轮踏面与TB 60钢轨匹配的名义等效锥度最大,与60D,60N钢轨匹配的名义等效锥度较小;LM_A踏面与TB 60钢轨匹配以及LM,S1002CN踏面与60D钢轨匹配时,具有较好的直线运行稳定性和曲线通过性能;LM,LM_A,S1002CN踏面与TB 60钢轨匹配时,车轮回复到对中位置的能力强;车轮踏面与60N钢轨匹配的接触斑分布均匀,直线上的磨耗性能好;LM_D踏面与TB 60,60D,60N钢轨匹配时也具有很好的磨耗性能;车轮踏面与60N钢轨匹配时,曲线通过的磨耗功最大,磨耗严重。
This paper analyzed and compared the contact geometry correlation between the wheel tread of LM,LMA,S1002 CN,LM（B-10）,LMD,XP55 and the rail profile of TB 60, 60D,60N by using Kalker CONTACT method to figure out the wheel-rail contact geometry characteristics.The results show that the wheel tread matching with rail profile TB 60 has a maximal norminal equivalent conicity,but it has a lower norminal equivalent conicity matching with rail profile 60D and 60N.The matching of LMA and TB 60,and the matching of LM,S1002 CN and 60D have a good performance of stability and curve passing.When the tread LM,LMA,S1002 CN matching with TB 60 rail, the wheelset has a better ability of return to the middle position.The contact patchs between wheel tread and 60N rail spread well proportioned,and the wear performance is good in straight line.The LMD tread also has a good wear performance when matching with TB 60,60D and 60N.When matched with the 60N rail, the wheels have maximal wear work,and are worn severely.
