The purpose of this study is to propose a technique for the identification of nonlinear system which has particularly high nonlinear viscous characteristics such as rubber and to simulate the transient response through a wide range of impact intensities. In this paper, the system is represented by a nonlinear Voigt model composed of nonlinear viscous element and nonlinear elastic element both forming polynomials. Objective data are obtained by taking repeated measurements using the multiintensity impact test for object identification. Using the accumulated data, the system parameters are calculated by multiregression analysis. The identification accuracy of the system was high when evaluated with estimated relative standard error (RSE)and mean RSE.
