The modeling of satellite micro-vibration isolators is the basis for further simulation, optimization and control of system vibration. Because the model of five-parameter fractional derivative cannot describe amplitude variable performance of the damping satellite vibration isolator, according to the experimental data, parameter identification of dynamic characteristic curves of isolator under different displacement amplitude excitation was conducted. According to the parameter identification result, the amplitude correlation correction were conducted to five-parameter fractional derivative model, and the amplitude variable factor was introduced. From the comparison between the simulation results and the experimental results, it can be seen that the modified fractional derivative model with amplitude variable factor can well predict the amplitude variable characteristics of the vibration isolator with hydraulic damping. Based on the proposed fractional derivative model, the influence of main model parameters was analyzed. The proposed modeling method can provide reference for the design and analysis of micro-vibration isolators.
