Shape design of an engine mount by a method of parametric shape optimization

Abstract

In order to obtain an automatically designed shape of engine mount, the authors introduce the shape design process using the method of parameter optimization. The optimization code is developed and used with a commercial non-linear finite element program to determine the shape that satisfies the stiffness requirements of engine mounts. A bush type engine mount used in a passenger car is chosen for the application model. The stiffness of the optimized model along the principal direction is compared to the design specification of the mount. The shape obtained from the parameter optimization is considered to be acceptable. It can be seen that a well-defined parametric approach is successful in the design of the basic shape of engine mounts.
