Dynamic Experiment of Large Space Remote Sensor

Abstract

Large space remote sensor's structure is very complex,and it's weight is heavy.In development process,the design of fixture is a difficult work.The fixture is a force transmission component in vibration tests,which connecting the shaking table and the remote sensor directly.Its performance will affect the reliability of the vibration test.The development of the fixture and the vibration test process was discussed in this paper.Sine vibration and random vibration results showed that the input from the fixture consistent with shaking table.Test results indicated that the fixture did not amplify and shrink the input conditions obviously,which verified the effectiveness of vibration test.
