| 摘 要： | 针对某型调距桨桨毂机构建立有限元模型，考虑将瞬时冲击作用等效为静力载荷，以惯性力的形式施加于桨毂机构上，并基于模态叠加的思想，求解等效静力载荷，进而获得该阶次模态下桨毂机构各构件的应力响应结果，最终计算调距桨机构中螺栓连接件的等效冲击应力。

| Abstract: | The FEA model of a certain CPP hub is built in this paper. The instantaneous impact is equivalent to static load exerting on the hubs in the form of inertial force. Based on the thought of modal superposition, we obtain the solution of the equivalent static load and the stress response of the hub institutions components under the relevant order of the mode, and then the final equivalent stress of bolt in this system is calculated. |
