一种基于智能传感器的刹车片缺陷检测方法

本发明公开了一种基于智能传感器的刹车片缺陷检测方法，属于制动无损检测技术领域。通过采集刹车片当前电信号与历史多周期电信号，提取时域振幅衰减、相位滞后、包络斜率、峰值间隔多维度声学特征构建时序特征矩阵；量化声波波形畸变因子与声学阻抗差异，定位刹车片缺陷三维坐标与结构破坏深度；提取缺陷扩展路径、速度与方向，构建波形畸变因子时序发展轨迹曲线，判定缺陷恶化趋势；时序建模预测未来周期频域、时域声学信号演变趋势，推算衰减至失效临界值预期时间，输出包含维护时间窗口、缺陷更换位置的预测性维护指令。本发明解决传统刹车片超声检测无法识别早期微观缺陷、不能追踪缺陷演化、无失效预判能力的技术问题。
