一种舵机振动夹具的设计

A Design of Vibration Fixture for Steering Engine

某型舵机圆柱外表面安装有舵面,无法使用上、下两组圆环形式固定舵机,研制了一种新型振动夹具,为圆盘形,较好地避免了夹具与舵机舵面的干涉。对所设计的振动夹具利用SolidWorks软件的Simulation模块进行模态分析,第一阶固有频率达到5 121 Hz,传递性良好,与试验件连接后进行调试,试验件上两个控制点振动响应良好。

The cylindrical surface of a steering gear is equipped with a rudder surface,so it is impossible to use the upper and lower groups of rings to fix the steering gear.A new type of vibration fixture is developed,which is disc shaped,and avoids the interference between the fixture and the rudder surface of the steering gear.The design of the vibration fixture using SolidWorks software Simulation module for modal analysis,the first order natural frequency up to 5121Hz,good transmittance,and the test piece after debugging,two control points on the test piece vibration response is good.
