Abstract: For overproof in high frequency region in 200N·m·s CMG Random Vibration real situation test,the primary factors for the overproof are analyzed,the solution of overproof in high frequency region Random Vibration test through improving the performance of vibration test fixture,and adding viscoelastic damper between vibration test fixture and shaker panel is proposed, which is confirmed by Random Vibration qualification test.

Key words: CMG, random vibration, overproof vibration
