The Achievement of Dynamic Load Simulator of Servo Mechanism of Multiple DOF Thrust Vector

Abstract:

In order to better analyze the load resonant characteristic of thrust vector servo mechanism of spacecrafts, multiple DOF mathematical models were established. Combined with the need of simulated actual conditions for ground tests, a comprehensive load simulator containing mechanical and hydraulic load was presented. The simulation results show that, the dynamic characteristics of output load displacement of the simulator is in agreement with the characteristics of actual system. The simulation and experimental results verify the feasibility of this load simulator structure, which could provide design reference for developing equipment of thrust vector control system for ground tests.
