Abstract

In closed hydraulic driving system with speed sensitive control, using the induction of DA valve to engine speed, the system can adjust the pump displacement automatically, and pump output power and engine input power can get the best match. On the basis of analysis of the speed sensitive control system working principle, the paper found out the influence parameters of variable pump control pressure. By the simulation analysis of the professional software of AMEsim, the paper verified the dynamic process of the influence of the parameters on the control pressure of variable pump, and provided reference for improving the working performance of the variable pump.
