Model Construction and Characteristic Analysis of a Hydraulic Drive and Physical Simulation System

A physical simulation system for the hydraulic drive is a product of the high and new technology that integrates mechanism,electricity,hydraulics,instruments,and computers,so that it can provide a surface simulation test platform before installation for the pieces of equipment and devices as used in the floating coordinate system,while offering space-attitude true values.Besides,this system can be used for personnel training.Through constructing a mathematic model in the system we could define transfer functions in the system while analyzing its stability and corresponding features so as to select a logic calibration network,thus realizing the stability and better response curves.This system performs a function of savings in R&D expense and shorter R&D intervals in terms of R&D in the equipment and devices as used in the floating coordinate system.
