Abstract:
Sea gravity measurement is conducted under dynamic conditions. In order to increase the measurement precision, eight hydraulic bumpers were used in the sea gravimeter sensor bucket of AIRSEA system II to decrease the perturbation of the survey boat; however, such problems as easy to aging and poor buffer still exist. Therefore, four new hydraulic bumpers were placed on the bottom of the sensor bucket to improve the stability of the sensor under severe weather conditions. . Numerical simulation and experimental data confirmed that the new hydraulic bumper can effectively extend the measurement range and acquire data with high accuracy.
