摘要

行星减速机在设计阶段采用的静强度设计理论

由于无法反映其在工作过程中所承受的动载荷

导致实际使用中故障较多。要想从根本上解决造成这种现象的原因

必须确定在不同任务剖面下行星减速机所承受的动载荷。传统载荷确定方法存在很大的局限性

随着计算机仿真技术在各行各业中的广泛应用

本文对不同任务剖面下进行行驶仿真试验

并在此基础上对行星减速机进行动力学仿真

获得不同任务剖面下行星减速机各零部件所承受的动载荷

并从疲劳损伤累积理论入手分析了在承受交变载荷情况下的最大应力远远小于设计最大应力很多倍的情况下

仍然会发生疲劳破坏的原因。本文以行星架为例提供了在不同任务剖面下其所承受的动载荷

为进行疲劳强度计算和寿命预测提供了重要的载荷参考数据。

Abstract

The static strength theory applied in the design process of the planetary reducer can’t reflect the dynamic loads suffered by it

so the faults of the planetary reducer are more than the imagination in running process.In order to solve the problem basically

the most important thing is the dynamic loads.The dynamic simulation of the planetary reducer based on running simulation is carried out

and the dynamic loads in different profile of the planetary reducer are obtained.By fatigue damage cumulative theory

the reason of damage under the working loads much lower than design loads is explained.The process of obtaining dynamic loads with the example of planetary frame in different profile is demonstrated.Important reference data of fatigue design and life prediction for planetary reducer are provided.
