Practical mechanical systems have hysteretic nonlinearity. The hysteretic characteristics have been expressed by various models, Ramberg-Osgood model, bilinear model and trilinear model, which were required to fit practical hysteretic characteristics by choosing parameters. In this investigation a method is proposed to describe measured hysteretic characteristics by Preisach distribution function. Numerical describing function was obtained by applying to the characteristic Fourier transform, which was combined with equation of motion. Thus frequency response was obtained from this analysis.
