Simulation Method of Active Adjustment of Large Reflector Antenna Based on Simplified Actuators

Because of its complex structure, the actuators are simplified in the simulation of active adjustment of large reflector antenna. The actuator achieves the purpose of adjusting panel position by applying load. The relation between actuators adjustment values and loads are given by finite element method. When the adjustment values are entered, the loads of actuators are calculated. When the loads are applied to the finite element model, the actuators adjustment accuracy are less than 10(-6)mm.
