Abstract

Engine mount is used to soften the impact of bumper with elasticity recovery and damping capacity. Inner noise and vibration to influence the comfortableness for passenger cause the engine to the chattering phenomenon. In this study, structural analysis can be done by engine mounts designed with 3D modelling. Natural frequencies and harmonic responses are analyzed by using models with some kinds of configurations. When the simulation model is applied by the force of 600N within the range of natural frequencies, the magnitude of deformation becomes 0 to 3mm. As the number of holes around inside mount increases, the capability of vibration absorption and durability becomes larger. In case of 5holes around inside mount, it can be safest on durability. The life of mount becomes larger by changing the configuration of model. The engine mount improved with durability can be designed through the result of simulation.
