摘　　要：针对某型调距桨装置桨毂组件进行了三维光弹性试验研究。试验中,采用环氧树脂材料制成了桨毂组件缩比模型。加载与冻结试验后,对样件切片并在光弹性仪的圆偏振光场中进行数据采集。根据切片上的条纹级数并结合应力—光学定律,得到各测点应力值及应力分布。试验结果可以为桨毂组件应力全局性研究和桨毂组件优化设计提供有效依据。The distribution of stress of a CPP hub is investigated with photoelastic method. In the research, a reduced scale test model is built with epoxy resin. After stress freezing, the fringe order is recorded by photoelastic apparatus, and the stress is obtained according to the stress-photics theory. On the basis, the stress distribution of the components of the CPP hub is obtained. The result of the photoelastic test can provide the support for strength check and optimization of the CPP hub.
