HXD1型机车牵引装置螺栓组有限元分析

Finite Element Analysis for the Bolt Group Stressof Traction Device on HXD1 Type Locomotive

对HXD1型机车牵引装置螺栓组加衬套前后的2种结构分别建立了有限元模型,进行数值模拟计算,结果表明加衬套后螺栓的应力降低约一半,螺栓组利用率偏低。

This paper established FEM models for bolt group stress of traction device on HXol type locomotive before and after adding bush. The numerical simulation calculation results show that stress has been reduced by about half after adding bush. The utilization rate of bolt group is low.
