Dynamic Simulation and Vibration Test of the Active Potential Controller

The Active Potential Controller was used to avoid the risk of damaging the life of astronauts outside spaceships in outer space by controlling the potential of the spaceship. This paper analyzed the structure of the Active Potential Controller by dynamic simulation, including setting up a finite element method (FEM) model, modal character and frequency response. At last, the designing and analysis was proved by the data from a vibration test. In this field, decreasing the weight was a key theme, the goal is cutting the cost. But cancelling or improving the sine vibration test could also save a lot cost, either for the payload or the satellite.
