Abstract

Vibration of exhaust system due to the engine operation and the condition of the road surface which is transferable to the body through the hanger affects the noise, vibration and harshness performance of the vehicle. The exhaust manifold is mounted on the engine and the exhaust pipe is fitted to the exhaust manifold. Therefore, the fixed-free condition of exhaust system finite element model has been used to perform normal mode analysis and frequency response analysis using MSC Patran/Nastran software. According to the simulation results, the average excited load response at the different nodes is generated. The root mean square (RMS) values of these responses were calculated to select the suitable hanger positions which are confirmed at the point where the RMS value is comparatively small. This study can contribute to the design development and verifying the performance of an automobile exhaust system and can be broadened for the other exhaust system designs of various vehicles.
