远程实时装载机液压系统故障监测的分析与研究

Research On Extraction of Fault Feature of Hydraulic System in the Loading Machine

以装载机液压系统工作齿轮泵压力信号为对象,利用数字信号滤波、快速傅立叶变换为工具,分析并提取了油箱少油工况下该信号的故障特征量,为装载机液压系统其他工况下的故障特征量提取提供了参考。

Based on the pressure signal of the operating gear pump,it uses signal filter,FFT transformation as analysis tool,and researches fault feature abstraction in hydraulic system of the loading machine when oil box is lack of oil.This provides reference for fault feature abstraction in other working case of hydraulic system.
