Analysis of Stress Relaxation Characteristics of Rubber Sealing Gaskets Under the Influence of Random Parameters

The Mooney–Rivlin hyperelastic model and Prony series viscoelastic constitutive model are used to verify the selected calculation parameters by finite element analysis compared with stress relaxation test data. Then, the ANSYS-PDS (ANSYS-probabilistic design system) module is used to analyze the sensitivity values of all random parameters to surface contact stress and the influence of hyperelastic and viscoelastic parameters on the surface...
