In automotive industry, rubber mounts are widely used to cushion the loads and isolate vibration in passenger vehicle compartments. In this study an engine rubber mount and strut bushing are analysed. The static and dynamic characteristics of the rubber specimen as well as the viscoelastic and hyperelastic properties are obtained by static and dynamic testing. The material properties coefficients in the finite element analysis have been implemented accordingly to the test data. The dynamic and static characteristics of the strut bushing and the engine mount are predicted with finite element analysis. The solutions show satisfactory agreement between predicted and experimental results. According to the authors, this work on the development of vibration isolation mounts using physical tests and simulations for verification of the final product, and providing the static and dynamic design factors represents pioneer work in open literature.
