Exhaust System Finite Element Analysis and Optimizing Design

Abstract:

The vibration of the exhaust system has led to cars vibration and high noise. Without doubt, they affect the performance and especially make the people particularly uncomfortable who ride in the car. The paper will resolve the trouble by the application software of the SOLIDWORKS. It establishes the exhaust system model then makes its finite element analysis of frequency to research the relationship between lugs hanging positions and amplitudes. Obtain a conclusion is to change the hanging position can reduce the maximum amplitude of the exhaust system. The article will show how to finish the all working process from building a model to getting the optimization scheme of reducing the exhaust system vibration and the best hanging position. Thus it provides a simple feasible method as the paragon of designing other parts.
