A Simplified Simulation Method of Actuators for Active Adjustment of Panels of Large Antennas

The structures of actuators are complicated. In the simulation process of active adjustment of large reflector antenna, it takes more time and effort to model the actuator, and the calculation time will be longer, so the actuator should be simplified. A short beam is used instead of the actuator to realize the simulation process of active adjustment of the antenna. The finite element method is used to give the relationship between the actuator adjustment and the load. The load of each actuator is calculated when the adjustment quantity is entered. Applying the load to ANSYS results in an error of less than 10
