The axisymmetric metal spring marine gravimeter is inevitably affected by carrier disturbance in dynamic measurement. Taking CHZ-Ⅱ marine gravimeter developed by Innovation Academy for Precision Measurement Science and Technology， Chinese Academy of Sciences as an example， we set up its measuring model by mechanical analysis under working condition， and analyzed the influence of carrier disturbance on capacitance micro displacement detection. The results show that the vertical disturbance acceleration of the carrier directly affects the output of capacitance micro displacement detection of CHZ-Ⅱ marine gravimeter. We also analyzed the influence of carrier disturbance on dynamic nonlinear error of the gravimeter. The conclusions are as follows： Disturbance acceleration from the carrier （such as survey ship， investigation boat） is the direct factor of the marine gravimeter's nonlinear error. The dynamic nonlinear error is positively correlated with the amplitude of disturbance acceleration and the frequency of disturbance acceleration. The research in this paper is of great significance to improving the dynamic measurement accuracy of marine gravimeter.
