THE OPERATION AND ANALYSIS OF ELECTROHYDRAULIC SERVO FORCE SIMULATION SYSTEM

This paper,by taking aircraft helm surface air dynamics simulation as example, presents the principles,procedures,results and analysis of experiments with an electrohydraulic servo force simulation system.It is a high-pass compound controlsystem with“artificial”and“movement”modes,wide frequency pass-band,andsatisfactory dynamical quality.In principle,it can exactly simulate any givenload pedigree.This method is suitable for force simulation in many respects such asstrength test and fatigue test.
