Abstract

To improve the performance of one exhaust system, in the article, a exhaust system in the market was conducted by the stress analysis and optimization of the hanger. Firstly, the 3D model was built by Catia and a FEM model was built by Hypermesh , and then the calculation of the free modes were done by Anasys. After that, with the method of component mode synthesis and then through the analysis by the software Nastran, the best hanger position was got. Finally, the optimized system was conducted the restrained modes analysis, and the reaction force of hanger was calculated as well,by verification and comparison, the modal mode of vibration is more appropriate,and the peak of the force has decreased, in the low frequency section,the curve is more smooth,the optimization was proved to be effective to improve the system’s NVH performance.
