英文摘要：

According to requirements of telescope FAST to deformation driving of main active reflector, a hydraulic scheme was introdueed. Based on this seheme, implementation methods of different working conditions were given out. Simulation models of the actuator based on AMESim were established to research the motion performance of tracking and servo. Experiment prototypes and testing platforms of the hydraulic actuator were built to verify the simulation results of the two working conditions. The comparisons indicate that the actuator scheme is reasonable, the consistency of two re- search methods is better and the performances can meet the demands of corresponding indexes. Meanwhile, the results show that the simulation can provide many reliable designing parameters and predict various dynamic properties.
