Design and analysis of engine mount for biodegradable and non-biodegradable damping materials

In the present automotive world high importance is given to the comfort and safety of the passenger. The comfort to the passenger signifies many terms such as the seating structure, leg space, air conditioning etc. The most important thing is that all the vehicles are subjected to vibrations such as from the engine or from external factors. The vibrations produced from the engine are transferred to the entire vehicle structure and this is reduced by placing engine mounts between the engine and the chassis. Designing the proper type of mount holds the key for effective reduction of vibrations. In this article a new design of the engine mount is proposed and taken into finite element analysis. Also, material for the mounts are considered to play a vital role. In this along with two regular materials, a biodegradable material is also used for the dampers. More importance is given to the frequency response of the mount for different materials and the finite element analysis is performed for a four-cylinder inline engine with two mounts on either side.
