英文摘要：

First,considering the working condition of actuator of radio telescope FAST＇s active reflector with velocity and driving force,an actuator transmission scheme of variable-frequency motor,worm gear and ball screw are proposed.Then,virtual prototype model of the actuator was built in ADAMS for its kinematics and dynamics simulation.Finally,through ADAMS and MATLAB,the coordinated simulation system of actuator was built and its performance testing was implemented.The result shows that actuator has preferable dynamics response characteristics and nicer locus-tracking ability,it can meet design requirement.
