bearing down

In order to investigate the dynamic characteristics of blade impact to droop stop,a moderate deflection beam model is adopted to deal with the elastic deformations,and the finite rotation is introduced to take account of the rigid motions around hinges.

针对铰接式旋翼桨叶扬起下坠碰撞问题,采用中等变形梁模型,同时引入有限转角模拟桨叶绕铰的刚性运动。
