THE RESEARCH OF THE DAMPER CHARACTERISTIC TESTING METHOD ABOUT DAMPER IN VACUUM

The damper characteristic is one of the main parameters of damper and need to be tested by the combination testing methods.In this paper,the buildup of damper characteristic testing system applied in the thermal-vacuum environment was described.The damper characteristic was tested in different rotate speed and different loaded moment,and the adaptability design to the thermal-vacuum environment was carried out.In the end,the testing results were introduced briefly.
