Designing of anti-vibration rubber mounts for an all-terrain vehicle for BAJA SAE

Abstract

Engine is the powerhouse for a combustion powered automobile. For the propulsion of automobile, engine must be mounted on vehicle safety. The way it is mounted on to vehicle is very important and plays a crucial role in determining the Noise vibration and handling (NVH) characteristics of an automobile. A proper designed mount should block the vibrations from the engine to automobile body and should not allow the effect of road unevenness on to the engine. Vibrations are generally due to power pulses during power stroke, which is reduced by properly designing flywheel, and unbalance of rotating and reciprocating parts, which is reduced to a maximum level possible and rest damped out at the mounts, generally, elastomers like rubber are utilized to damp the vibrations. When comes to All Terrain vehicle, mounts are under heavy loading conditions due to terrain on which vehicle is used. This paper discusses about the designing of such mounts to be used on BAJA SAE buggy.
