Scanning mechanism and truss reflector are important components of antenna. Aiming at the mechanical system and control system composed of scanning mechanism and truss antenna, the co-simulation technology of hybrid stepping motor and flexible dynamic mechanism is proposed. Through the simulation results of the current and position changes of the antenna system, the various physical characteristics of the system during the co-simulation are studied, and the vibration characteristics of the overall antenna system are analyzed, which verifies the cooperative ability of the antenna mechanism system and the control system.
