粗糙面接触的显微光弹性分析及其若干问题

Microphotoelastic stress analysis of rough interface contact and some problems

采用显微光弹性方法，按非线性问题的模型理论，确定了涡轮盘上叶片在任一几何形状时的榫头与榫槽六个接触面、非接触自由空边及指定分析截面上的应力光图．给出了它们的应力分布曲线。

The stress patterns and distribution curves of six contact interfaces and non contact free edges are given by using microphotoelastic method according to the nonlinear model similar theory for a specific plane tenon and mortise. These results provide the experience and enlightenment to the further study and engineering design of non ideal surface contact stress analysis.
