Reduction of Stresses and Mass of an Engine Rubber Mount Subject to Mechanical Vibrations

A rubber engine mount (EM) is a mechanical coupling between the and chassis, its main function to diminish, in amplitude of vibrations caused for operation. Such cause discomfort vehicle passengers reduce EM lifetime. To increase comfort lifetime EM, this paper presents an optimization by means reducing three criteria: mass, displacements transmitted stress core. For carrying out optimization, optimum global determination linking interchanging kindred evaluators (GODLIKE), assisted artificial neural networks (ANN) finite element method (FEM), was used. Because process, reduction greater than 10 % achieved criteria comparison with baseline design. The frequency responses were compared showed that although carried range 5 Hz 30 trend reduced continues beyond range. These results increased EM; addition, mass diminishes production costs.
