摘要：
The main function of an exhaust system is to control the noise and to funnel exhaust fumes. The catalytic converter is designed to reduce the amount of harmful emissions products by transforming pollutants into water vapor and less harmful gases. Converter's modal parameters such as frequency, damping and mode shapes play a significant role in functioning of an exhaust system. The influence of the thermal expansion unit of the close coupled catalytic converter on the exhaust system and experimental modal analysis of catalytic converter is presented. It is observed that there is good correlation between the calculation results based on finite element analysis and the results obtained from experimental modal analysis.
