摘要:



利用测试系统对某液压设备的管路进行数据采集,对液压系统工作时管路在正常状态与裂纹故障状态下采集到数据通过利用小波多分辨率分解得到各频带信号能量分布作为特征参数,进行分析比较、识别和处理。实验结果表明:小波分解各频带信号和能量分布可以作为管路裂纹故障的识别和判断依据。

The test system is used to acquire data on hydraulic pipeline. With wavelet transform, characteristic pa- rametrs of energy distribution for acquired signal of hydraulic pipeline under normal and crack fault condition on different bands are obtained, compared, identified and treated. Experimental results show that the signal with wavelet transform and energy distribution on different bands can be the identification and judgement basis for pipeline crack fault.
