Abstract
A rubber bush used in an automotive suspension system is an important element for the ride comfort and the driving stability. The relation between the applied force to the rubber bush and its deformation is non-linear and shows a feature of viscoelasticity. In a real-time analysis of a vehicle model with the rubber bush, it becomes a subject of discussion how to express the characteristic of the rubber bush with a simple model. In this study, modeling method for rubber bush based on evaluation test was considered. A generalized maxwell model was used for the bush model. In order to identify the model parameters based on measurement results, evaluation test of viscoelastic material was conducted.
