Dynamic mechanical properties of ZN-35 silicone rubber materials based on H-N model

Abstract

ZN-35 silicone rubber is a kind of effective vibration damping material in aerospace, which can be made into a vibration damping pad for preventing vibration and damage to important components in the rocket. In this paper, the energy storage modulus and loss factor of ZN-35 silicone rubber materials at 11 different temperatures were tested by DMTA . The dynamic mechanical properties of the materials were analyzed at different temperatures. Finally, through the selection and fitting of data, the four parameters( ,  , 0 E , E  ) of H-N model is determined. Meantime the H-N model curve is drawn. The dynamic mechanical properties of the materials are provided by using the H-N model, which provides the basic data for the use of vibration damping materials and the design of shock absorber.
