Abstract:

All machines, vehicles and buildings are subjected to dynamic forces that cause vibration. Most practical noise and vibration problems are related to resonance phenomena where the operational forces excite one or more modes of vibration. Modes of vibration that lie within the frequency range of the operational dynamic forces always represent potential problems. Mode shapes are the dominant motion of a structure at each of its natural or resonant frequencies. Modes are an inherent property of a structure and do not depend on the forces acting on it. On the other hand, operational deflection shapes do show the effects of forces or loads, and may contain contributions due to several modes of vibration. This project deals with optimization and modal analysis of the upper arm suspension of double wishbone suspension. Upper arm has been modeled using CATIAV5, meshing will be done in HYPERMESH12.0, and ANSYS will be used for post processing. Boundary forces will be calculated. Static analysis will be done which is needed to be done for optimization, low stressed region will be identified and material will be removed from that region. Re-analysis (modal) will be done on the modified model. Once we get desired results, model will be fabricated and tested with FFT analyzer to check for response of the arm. Suspension system of an automobile plays an im1portant role in ensuring the stability of the automobile. Control arm plays major role in independent suspension system. It is generally made of forged steel which has considerable disadvantages such as weight, cost etc.
