AP 1 000 MW nuclear steam turbine unit has the greatest capacity and the largest operation parameters among the nuclear power generators in the world. The servomotor is the actuator of the steam turbine governing and safety system; which imposes strict requirement for its quick closing buffering characteristic. Taking buffering in quick closing process of the conical piston of the hydraulic cylinder in the servomotor as the main research objec-tive, building mathematical model in considering of buffering mechanism, then simulating and experimental study on buffering characteristic, providing theoretical basis for servo motor of the hydraulic cylinder cushion structure de-sign.
