Abstract：Starting from the physical mechanism, the nonlinear equivalent dynamic models of discrete isolation system was set up by the deformation of the cubic polynomial function and fractional derivative operator, and the vibration transmissibility from the bottom of the isolator to the satellite was obtained by harmonic-balance method, also the phenomenon of vibration isolation platform affected by excitation magnitude was explained from the physical mechanism by numerical solutions, providing references for the design and practical application of discrete whole-satellite vibration isolation platform.
