Design Optimisation of Engine Mounting Bracket using F.E.A. Software

Reduction of engine vibrations and the dynamic forces transmitting from engine to the automotive body structure has always been an important part of automotive research. Automobile engineers face the task of creating a mechanism to absorb these vibrations and provide a smooth ride. Usage of Motor Mounts is the best solution for dampening the effects of vibrations and oscillations. Present weight of the engine mount bracket in the vehicles used for V16 engines is approximately 1340 gms. Industry is aiming to further overall weight reduction of the vehicle¿s components. Weight of the mount bracket is another characteristic parameter considered for structural optimization analysis. Objective of the analysis is to minimize the weight of the mount bracket without varying the overall performance of the component. A finite element analysis is performed on the model for suitable loading conditions and constraints. Design optimization feature is used to work on the parameters considered and to arrive at a convergent solution.
