摘要 含金属芯压电纤维(Metal-core Piezoelectric Ceramic Fiber,MPF)是一种新型压电功能器件。介绍了MPF的结构及其对圆形压电片激励Lamb波的传感响应模型。利用Gabor小波变换计算损伤反射信号到达时间延迟的原理,把MPF传感单一模式Lamb波在一维结构中进行了损伤定位研究。研究结果表明:MPF可以进行Lamb波的单一模式传感,采用Gabor小波变换计算损伤反射信号到达时间延迟效果较好,损伤定位精度较高。 Metal-core piezoelectric ceramic fiber（MPF） is a new type piezoelectric ceramic device.Its configuration and response to Lamb wave fields excited by a circular crested actuator were presented here.According to calculating time delays of damage signals with Gabor wavelet transformation,MPF sensing single-mode Lamb waves to be used in one-dimensional structural damage localization was investigated.Results showed that MPF can be used as a sensor for single mode Lamb wave;its performance of calculating time delays of damage signals with Gabor wavelet transformation is good;the damage localization accuracy is also high.
