摘　　要：为了研究对置端曲面齿轮柱塞泵参数对泵动态特性的影响,根据端曲面齿轮柱塞泵工作原理,推导柱塞运动方程。利用Adams与AMESim软件建立对置端曲面齿轮柱塞泵联合仿真模型,通过联合仿真得到不同转速与偏心率下的柱塞泵出口流量与压力的相应曲线。结果表明:转速增大,泵出口流量与压力增大,脉动幅值与脉动频率增大;偏心率增加,泵出口流量与压力增大,脉动幅值增大,脉动频率不变。In order to study the influence of opposed end curve-face gear piston pump parameters on the dynamic characteristics of the pump,the motion equations of the plunger were derived according to the operating principle of the end curve-face gear piston pump.A joint simulation model of the opposed end curve-face gear piston pump was established by using Adams and AMESim software,and the corresponding curves of the outlet flow and pressure of the piston pump at different rotational speeds and eccentricity were obtained by the joint simulation.The results show that as the speed increases,the pump outlet flow and pressure increase,and the pulsation amplitude and pulsation frequency increase;as the eccentricity increases,the pump outlet flow and pressure increase,the pulsation amplitude increases,and the pulsation frequency remains unchanged.
