摘　　要：巴克豪森效应是电磁方式检测材料微观结构和应力的基础。通过试验方法分析不同激励频率、激励电压和激励波形下巴克豪森噪声信号的时域、频域特征,研究激励信号参数对材料应力检测的巴克豪森信号特征值的影响,并探究现象的微观解释。Barkhausen effect is the basic of the detection of micro-structure and stress. The features of Barkhausen noise is shown in this paper, under the excitation with different voltage, frequency and wave. While testing the sample, the effect of stress on Barkhausen noise due to the parameters of excitation is studied and the explanation in microscopic field is discussed.
