| 摘 要： | 为了研究航空涡桨发动机桨轴在飞行试验中所受的载荷问题，对某型发动机桨轴进行几何建模，并运用有限元软件ANSYS对桨轴在离心力、拉力、扭矩和弯矩作用下的应力进行了仿真计算，得出了起飞状态下的应力分布，对桨轴贴应变片部位的应力进行了分析，得出弯矩影响最大、扭矩次之、离心应力可以忽略的结论，为飞行试验提供了理论参考数据。

| Abstract: | To study loads of propeller shaft in flight test, its model was created. The stress with centrifugal load, pull, torsion load and moments was calculated. The results showed that torsion load and moments were the most important and centrifugal load could be ignored. This study gave a good reference for flight test of propeller shaft. |
