摘　　要：针对传统水液压柱塞泵输出流量脉动大、振动噪声高的问题,研制出一种以直线电机作为动力端的直驱水压柱塞泵.为减小直线电机换向对泵体产生的振动冲击,消除多个电机运行时的相位误差,实现柱塞泵低振动、流量稳定输出,对直线电机单直线电机控制模式、多电机协同控制策略以及电机运动顺序进行研究试验.试验结果表明:4台直线电机在SPLINE运动模式下以三角波曲线在插补点同步,按照优选出的启动顺序运动是实现柱塞泵低振动,输出流量稳定的最佳控制方式.Owing to the big output pulsation and high vibration noise in traditional water hydraulic piston pumps,a water hydraulic pump driven by the linear motor was developed. To reduce the impact of vibration on the pump body when the motor reverses,to eliminate the phase error of multiple motor at runtime,and to realize the low vibration and constant flow output of piston pump,the single linear motor control mode,motor coordination control strategy and motor moving sequence were studied. Result shows that the optimal control method for reducing the vibration of the piston pump and keeping the stability of flow is that the four linear motors should start in optimized boot sequence,with running in triangular wave curve and interpolation synchronous control method under the SPLINE movement mode.
