采用 I- DEAS软件的 FEM模块对三维弹性接触问题进行了二次开发 ,用间隙元法计算了轴流式转轮体、轴瓦与叶片枢轴的接触应力 ,所得结果比不考虑接触更为合理 ,从而为分析转轮体的强度提供了依据
The FEM model of I-DEAS software was used to develop the 3D elastic contact problem. The contact element stress was calculated by the gap element method, which was more reasonable than that without considering the contact , Which provides the basis for the analysis of the strength of the wheel body
