| Summary: | In order to explore the dynamic and static response performance of the multiflexible electrohydraulic position servo system, this paper mainly takes the electrohydraulic position servo system with elastic link as the research object, mainly including the hydraulic spring stiffness, the load spring stiffness and the mechanical connection stiffnessThe effects of multiple positions of the elastic link on the system, derived mathematical models including hydraulic cylinders, loads, servo valves and pistonsBased on the analysis of the stability and dynamic and static characteristics of the electrohydraulic position servo system, the importance of considering the existence of multiflexibility spring stiffness on the overall performance of the system is discussedThe research results show that the difference of the position of the feedback point of the system has different effects on the stability of the systemAt the same time, due to the existence of the mechanical connection stiffness, the dynamic and static response performance of the system also has a great influence |
