摘　　要：该文针对变量泵压力控制元件对变量泵的压力输出特性进行研究,通过模拟仿真研究压力控制阀上阻尼孔尺寸和弹簧刚度的影响规律。研究结果表明阻尼孔尺寸增加,减小变量泵输出压力的稳定时间,同时增大变量泵的泄漏量,压力输出偏差也会增大;调压弹簧刚度增加导致变量泵压力响应速度降低,同时泵的输出压力偏差会有所增大。This paper investigates the pressure output characteristics of a variable pump with respect to the variable pump pressure control element.The influence of the damping hole size and spring stiffness on the pressure control valve is studied through simulation.The results show that an increase in the size of the damping hole reduces the stability time of the output pressure of the variable pump,while increasing the leakage of the variable pump and increasing the pressure output deviation;an increase in the stiffness of the regulating spring leads to a reduction in the pressure response speed of the variable pump,while the output pressure deviation of the pump will increase.
