本文在某支撑座结构模型宽带随机振动实验的基础上，研究了如何监测连接螺钉组松动故障程度的问题。
On the basis of broad-band random vibration test on a clamping support in a missile, wavelet packet analysis method was used to obtain the reduced features of structural response signals, which have non-stationary characteristics due to the attachment bolt looseness.
在某导弹支撑座模型宽带随机振动实验的基础上，针对其连接螺栓松动所产生的支撑座结构响应的非平稳特性，采用小波包分析的方法得到缩减的信号特征；
Some unknown problems can also be found during the product testing. At Present, a variety of broad-band random and sine vibration control system has been developed and widely used in many kinds of fileds.
