摘　　要：为进行液压流体脉动的主动消振,设计了基于压电陶瓷的直接驱动伺服阀,并利用AMESim液压仿真软件对其进行了建模与仿真,并在伺服阀实验台上对其进行了静态试验。仿真与试验结果表明,所设计的压电陶瓷直接驱动伺服阀满足液压流体脉动主动控制要求。For active control of the hydraulic fluid pulsations, a piezoelectric direct drive servovalve has been designed and the modeling and simulations of the servovalve has been done through the hydraulic simulation software AMESim. Then static test on the servo-valve has been done on the servovalve test-bed. Simulation and test results indicated that the designed piezoelectric direct drive servovalve satisfied the active control of the hydraulic fluid pulsations.
