摘要
In the survey of the airborne gravity system,high frequency vibration caused by aircraft engine and airborne environment affects the precision of airborne gravity system measurement seriously.Aimed at solving the problems existent in the airborne gravity vibration reduction system,the authors made several vibration tests,and the result shows that the natural frequency can avoid the periodic vibration frequency of aircraft engine.In the frequency band of 100～500 Hz,the vibration transmissibility for the measuring point 1 is from -18 to -38 dB,and the vibration reduction effect is quite obvious.
