Summary: 
This study is concerned with modeling an elastomer impact problem when a mass experiences a collision with the contact pad mounted on the underlying linear dynamic structure. The contact pad which consists of the viscoelastic material is modeled by a linear or nonlinear contact stiffness and the analytical form of frequency response obtained by a Fourier spectral analyzer is utilized in modeling the underlying dynamic structure. One linear model and one nonlinear model are introduced and their characteristics are analyzed. The result shows that the predicted impact forces match the measured responses fairly well.
