Aerospace Hydraulic Actuator High Precision Performance Simulation Model Study
A high-precision performance simulation model construction method is proposed to analyse the influence mechanism of fluid elastic modulus change,energy loss in pipeline,servo valve zero position offset and other factors on the performance,and amend the basic functional model in the form of equivalent damping and equivalent spring,so as to build a high-precision performance simulation model of aviation hydraulic actuator.And the accuracy of the simulation model is verified based on the slope response test,which reaches more than 92％,proving the reliability of the high-precision modelling method of the article.
