设计了一个基于VC＋＋6．0的振动时效应力消除系统。系统通过接受AD芯片采集的激振器震动后产生的应力数值信息，将数据作FFT变换。数据处理后得到振动过程中，共振峰峰值和相应的转速值大小，并根据激振器振动过程中的加速度变化，寻找振动时效的亚共振区域，系统将控制激振器持续震荡，逐渐逼近峰值，可以达到更好地消除应力的效果。电机转速的控制算法采用Pl算法，控制芯片采用STM32。

The vibratory stress relief system is designed based on VC++6.0.The system accept stress data after vibration by AD acquisition chip,and do the FFT transform.After data processing,the system get the peak and the corresponding ro-tational speed of the formant,and according to the acceleration changes between vibration to find the sub-resonance area, then the system control continuous vibration to approaching the peak.The system can achieve better effect of stress relieve. The control algorithm of the rotational speed using the algorithm of Pl,the control chip using STM32.
