单轴雷达天线机械系统的动力响应

Dynamic Response of Single Shaft Radar Antenna Mechanical System

应用Ｌａｇｒａｎｇｅ方程和有限元法建立了由二个弹性体组成的有高精度要求的单轴雷达天线机械系统动力学方程并结合工程实际给出了天线匀速旋转时的方程和算法。

The single shaft radar antenna is a mechanical system of two flexible bodies. Based on the lagrange equation and the finite element approach, the dynamic equation of the antenna is established. From the practical consideration, the equations and the calculation method are presented when the antenna rotations perminute is constant. The antenna motor torque and displacement responses are given when the velocity of wind is 20m/s.
