摘要
模拟车载高架雷达在野外使用时受到风载,用应力应变电测法对其进行静力强度的测试,用脉冲锤激励法测量整车固有频率,给出主要结构件的受力情况及整车的固有频率。
For simulating wind load on vehicle-borne elevated antenna radar under field condition, test of its static strength are performed through electrically measuring stress, distrotion, and the inherant frequency of the whole vehicle with the method of impulse hammer exciting. In this paper the main construction parts and the inherant frequency of the whole vehicle are described.
