Abstract: Abstract: The continuous rotary cam-rotor vane motor, a kind of hydraulic servo element to convert fluid potential energy to mechanical energy, is the appropriate actuator for the hydraulic servo system which has good performance requirements. The parameter optimization design method which focuses on the transition curve segment of the camrotor outer contour was proposed herein. The relationships between the pressure angle and the disturbing torque, the flow fluctuation rate, the leakage and the central angle of transition curve were obtained based on theoretical derivation and analyses. Theoretical basis was conducted and optimized parameter of this kind of vane motor was obtained through analytical calculation and simulation. Experimental verification indicated that the camrotor vane motor had a very good servo precision and proved the feasibility and validity of the parameter optimization design method.
