Abstract：The experimental research of dynamic characteristics of rubber isolator was conducted, and the signals which collected from experiment were analyzed by using FFT. The neural net that the feasibility was verified by the curve reconstructed method, was used to fit the experimental curves. Based on the data exporting from the neural net, the parametric identification for polynomial model to describe the dynamic characteristics of rubber isolator was processed by employing the method of optimized least square. It is indicated that the relationship between damping, stiffness and the amplitude, frequency is surface. The least square method was used to fit the surface of damping and stiffness, and the constitutive relationships for describing the damping and stiffness of rubber isolator was obtained.
