【Abstract】 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.更多还原
