基于振动可视化的机械系统级故障诊断方法
摘要
Abstract
Based on the vibration visualization technique and system-level fault diagnosis theory, a new fault diagnosis method is presented for complicated machinery system. Firstly, the vibration signal is enriched all-sidedly by vibration visualization technique. Since the vibration signal contains plenty of time-frequency message, which varies from the obtaining point according to the machine construction, it can be used for the input of the system-level diagnosis model. Secondly, the analysis result of the multichannel vibration signal by local wave method is set as the input, and the prescribed system-level diagnosis model is brought in, before which the simply moving parts are set as the research object for the visualization technology application feasibility. In the specific diagnosis process, the test chart and the diagnosis chart are established orderly, as the result, the fault source is found out by group algorithm. The applied case illustrates that the fault diagnosis method based on vibration visualization and system-level model is effective in fault diagnosis for complicated machinery system.关键词
