摘　　要：某型机载雷达组件在综合应力试验后,振动夹具和组件出现了明显的结构破坏。为了探寻故障原因,对振动夹具施加白噪声激励,并分析其一阶共振频率。发现造成故障的原因是试验过程中发生了共振现象。通过对夹具进行的优化改进,避开了激励的共振点,并在实验验过程中利用实时监测的方法检测振动响应,避免故障现象复现。After multiple stress test,structure damage comes to the airborne radar components and vibration tong.To find the reason,vibration tong is stimulated by white noise and its first-order resonance frequency is analyzed,resonance phenomenon surfaced.To avoid resonance point,vibration tong was optimizated.The real-time monitoring is applicated in the multiple stress test to avoid reproduction of structure damage.
