位标器传动装置扭转振动固有频率及模态分析

Torsion Vibration Natural Frequency and Modal Analysis of the Target Seeker Gearing

对某位标器的三级圆柱齿轮传动装置进行简化等效处理,应用Patran/Nastran有限元分析软件对简化后模型的固有频率和模态进行分析,找出传动装置的薄弱环节和改进方向,为位标器传动装置的设计提供了一种快速有效的方法。

A simplified equivalent model of three-stage cylindrical gearing device for a target seeker is obtained. The natural frequency and modal of this model are analyzed with Patran/Nastra, and then the weakness tache and improvement way of gearing device are found, it provides a fast and effective means for design of the target seeker gearing.
