As per current automotive market demands, low cost and light weight components to meet the need of fuel efficient and effective vehicle. This in turn gives rise for more effective use of materials for automotive parts which can reduce the curb weight of the vehicle at same time enhance its performance. Reducing weight gives multi-disciplinary challenges in case of stiffness, NVH, strength and fatigue life requirement.
An automotive engine-body-chassis system typically subjected to unbalanced engine forces, uneven firing forces, dynamic excitation from gear box and also road excitation. Engine mounting arms always suffers fluctuating forces, which may results in fatigue failure, when component can break suddenly without any prior information. This fatigue of component under cyclic load is called fatigue. Our main focus is to optimize the design of engine mounting arm for fatigue life.
In the automotive field, fatigue strength of the component is predominant and often drives the design. The fatigue life of the engine mounting arm is evaluated based on static strength. The static strength of the engine mounting arm is evaluated using FEA software's subjected to vertical and breaking forces. The design is evaluated using von mises stress theory of failure.
