摘　　要：针对偏心轮式径向柱塞泵存在的柔性冲击和流量脉动问题,从改变柱塞杆运动规律入手,通过2种运动规律的组合,设计一种特殊轮廓曲线凸轮。通过2个泵原件的组合,该凸轮柱塞杆在一定时间段内无流量脉动。仿真结果表明,该柱塞泵凸轮设计可行且总流量恒定。Aiming at the problems of flexible impact and flow pulsation in eccentric radial piston pump,a special contour cam is designed by changing the motion law of piston rod and combining the two motion laws.Through the combination of two pump components,the cam plunger rod has no flow pulsation in a certain period of time.The simulation results show that the design of the piston pump cam is feasible and the total flow is constant.
