The research on three axis-six DOF disturbance force test technology and its application

The spacecraft micro-vibration mechanical environment will have significant effect on the spacecraft performance. To research the micro-vibration influence, a new disturbance test technology is proposed based on FRF inverse theory. The technology can be used to measure three axis-six DOF disturbance forces of any moving parts on the satellite, so it can be applied to evaluate the vibration influence to the satellite environment. An application of the technology is given in the paper as an example. The technology will have broad application prospects in the field of space.
