液压系统软参数的确定与故障诊断

Determination of soft parameters and trouble diagnosis in hydraulic system

本文基于实测频率特性,利用系统辨识程序确定了试验台的实际模型,快速、准确地确定了液压系统中的软参数,进而查明了系统动态特性较差的起因。

This paper establishes actual model of test stand by means of system identification program based on practically measured frequency characteristics, determines rapidly and accurately soft parameters in hydraulic system, and then finds out the cause of poor dynamic characteristic of the system.
