【摘要】：针对复杂行星齿轮变速箱故障诊断问题,设计了一种某型装甲车辆行星变速箱故障模拟试验台,并选择不同状态下的振动信号进行了故障特征提取。首先,简要介绍了PGB-A行星变速箱的结构和工作原理;其次,设计了该行星变速箱的故障模拟试验台和增速箱,设置了机械和液压故障并布置了测试传感器;最后,利用数据采集系统对该行星变速箱的各状态信号进行了采集,并应用排列熵算法对采集到的数据进行了故障特征提取。结果表明:该故障模拟试验台能够完成多种故障状态的试验,为复杂行星变速箱的故障诊断提供了数据支撑,且所提故障特征提取方法能够很好地检测故障。
[Abstract]:Aiming at the problem of fault diagnosis of complex planetary gear gearbox, a fault simulation test-bed for a certain type of armored vehicle planetary gearbox is designed, and vibration signals in different states are selected for fault feature extraction. Firstly, the structure and working principle of the PGB-A planetary gearbox are introduced briefly. Secondly, the fault simulation test rig and the speedup box of the planetary gearbox are designed, the mechanical and hydraulic faults are installed and the test sensors are arranged. The state signals of the planetary gearbox are collected by the data acquisition system, and the fault features are extracted by the permutation entropy algorithm. The results show that the fault simulation test rig can complete many kinds of fault state tests, and provides data support for fault diagnosis of complex planetary gearbox, and the proposed fault feature extraction method can detect faults well.
