基于门限关联度的传动箱 性能检测方法研究
Gear Box Performance Test Based on Threshold Relevance Degree
-
摘要: 使用振动加速度传感器获取传动箱振动信号,应用概率统计方法建立了传动箱标准正常状态模式,并计 算振动信号与标准正常模式的门限关联度.结果表明,所得门限关联度可以反映传动箱当前的性能状况,全部检 测过程均在计算机上进行.Abstract: Standard normal patterns for gear boxes were established with statistical method and by analyzing vibration signals acquired from the gear boxes with a vibration acceleration sensor. Then the threshold relevance degree between the vibration signals and the standard normal patterns was calculated. Experimental result on a wheel box shows that the calculated threshold relevance degree is a good parameter to reflect the performance of the gear box under experiment. The whole test can be conducted with the help of a computer.
