Shape design of an engine mount by a method of parameter optimization. (English) Zbl 0921.73210

Summary: In order to obtain an automatically designed shape of engine mount, we introduce an optimum shape design process of engine mounting rubber using a parametric approach. The optimization code is developed to determine the shape to meet the stiffness requirements of engine mounts, coupled with a commercial nonlinear finite element program. A bush type engine mount being used in a passenger car is chosen for an application model. The shape from the result of the parameter optimization is determined as a final model with some modifications. The shape and stiffness of each optimization stage are shown, and the stiffness of the optimized model along the principal direction is compared with the design specification of the current model. Finally, an overview of the current status and future works for the engine mount design are discussed.
