摘要
分别介绍了声发射(AE)信号归原处理法及小波包能量系数法的相关概念,提出了基于AE信号归原处理法及能量系数法相结合的砂轮磨损状态检测方法。实验结果表明,该检测方法能够有效地判断砂轮磨损的状态,并具有良好的可操作性。
The conception of restore processing method of the AE signals and capacity coefficients of the wavelet packets were introduced. A monitoring method for grinding wheel based on restore processing method of the AE signals and capacity coefficients of the wavelet packets was advanced. It is indicated that this method cam preferably distinguish grinding wheel states, and it has a preferably maneuverability.
