Abstract

Simulation and experimental research for the dynamics characteristics of steering PUM based on speed compensation

Author(s): Chen Lei, Zhang Pan, An Ji

In view of steering pump of automobile hydraulic power steering system has the problem of larger energy loss, put forward a kind of speed compensation type hydraulic steering pump which contains variable mechanism; the pump can effectively reduce the energy loss in the normal condition of steering pump. Using the method of complex plane to analyze the variable mechanism dynamic characteristics of new steering pump with speed compensation, build dynamic equations of variable mechanism and through simulation and prototype test studies the motion law of variable mechanism, verify and improve the dynamic equations of variable mechanism, establish the foundation of organization optimization and flow output equation of new pump
