某直升机螺旋伞齿轮三维光弹性应力分析

Three-dimentional Photoelastic Stress Analysis for Helical Bevel Gears of the Helicopter

采用硅橡胶－环氧／石膏制阴模技术，ＧＴＦ—１８２光学图象数字分析系统，对形状极其复杂的螺旋伞齿轮进行了三维光弹性应力分析，对改善该齿轮付的工作应力状态提供了可靠的实验数据。

Using silicone rubber-epoxy/gypsum making femal mold technology and GTF-182 digital optical pattern analysis system, the authors analyse three-dimentional potoelastic stress for belieal bevel gears that have complex form,and the reliable data obtained are useful to improve the gear operation.
