摘　　要：以电动舵机系统为研究对象,通过建立舵机系统刚柔耦合动力学仿真模型,重点研究了关键零部件柔性体变形及载荷对舵系统输出响应的影响关系。相比纯刚体模型,柔性体变形可提高系统的稳定性,零部件的柔性变形可导致响应曲线出现“削波”现象,而改变载荷对刚体模型响应输出影响较大。The electromechanical actuator system is selected as the object of this study.By establi-shing the rigid-flexible coupling model of the electromechanical actuator system,the effect of flexible deformation of key parts and the load on the rubber system output is emphatically researched.Compared to the rigid model,the flexible body deformation can improve the system stability,components’flexible deformation can lead to the clipping phenomenon on response curve,and changing load has more effect on the respond output of rigid model.
