摘要: 利用离散小波变换的时频特性和连续小波变换检测信号边沿的原理,进行模拟导弹运输 车辆轮胎和板簧的故障检测、分离和定位.该方法不需要对象的数学模型.模型车的故障诊断实验 结果表明.该方法灵敏度高,对噪声具有较好的鲁棒性.Abstract: This paper proposes a new approach to fault detection and location for tyres and springs of a missile transporting vehicle. The time-frequency characteristics of discrete wavelet transform (DWT) and local maxima of modulus of continuous wavelet transform (CWT) are used, and no model of the monitored object is needed in this method. Experimental results on a model vehicle show that it is sensitive to faults and robust to noise.
