动力系统在运行过程中，会产生诸如结构约束的松驰，内部裂纹的出现等问题。这些问题会引起结构动态特性的变化。将压电陶瓷片布置在结构表面，可以监测其动态特性及其变化，进一步辅以计算机人工神经网络技术，可以识别引起结构动态特性变化的原因和约束松驰的位置。
Power system in operation, will have such as structural constraints relaxation, the emergence of internal cracks and other issues. These problems can cause structural dynamics to change. Placing the piezoelectric ceramic sheet on the surface of the structure can monitor its dynamic characteristics and changes, further supplementing with the artificial neural network technology of the computer to identify the cause of the change of the dynamic characteristics of the structure and the location of the restraint relaxation.
