工程应用中的随机振动试验技术研究

Study on Random Vibration Testing Technique in Engineering Applications

阐述了机载电子设备随机振动试验的分类 ,并对宽带随机振动谱型的计算方法 ,振动推力及位移的指标进行了分析探讨。研究了试验的实用技术及控制方式的选择要点。最后给出了一个机载电子设备振动故障分析的例子。

The classification of the random vibration testing of the airborne electronic equipment is expounded. Also the computing method of the wide band spectrum of the random vibration and the targets of the vibration thrust and displacement are analyzed and discussed. In addition, the testing's practical technique and the selective gist of the control methods are studied and introduced separately. Finally, an analysis example of vibration troubles of airborne electronic equipment is given.
