Abstract
Recently, it has been important to develop light, silent and less-vibrational automobile. In this study, in order to investigate the characteristics of the noise caused by the main silencer components-stiffener flange, inlet pipe and exhaust pipe etc., computational flow analysis, vibration and noise experiments were performed about the variable heights of the stiffener flange. Flow structure in the mainsilencer which calculated by CFD solver-IDEAS ESC, and frequency response function results of impact hammer test was proposed and it was found good agreement between former results and the exhaust orifice noise measured.
