摘　　要：根据噪声信息流的传播途径研制了固体声传感器和检测系统，并采用全息频谱法分析处理固体声信息，以确定轴承的运行状态。实验结果表明，将此方法用于轴承故障识别时，能确切提取反映轴承工作状态的信息流。In order to make a diagnosis of the operating conditions of bearings in a mechanical system,an ac oustic noise detecting system,including its solid state sound transducer,and a holospectrum analysis of detected signals are developed according to the propagating path of the acoustic noise information flow.Experiment result shows that the method developed in the paper can accurately extract the information flow of bearing operating conditions for the fault diagnosis of the bearing.
