Summary:

Operational Modal Analysis, also known as Ambient Modal Analysis, has an increasing interest in mechanical engineering. Especially on structures where the excitation and not less important the determination of the forces constitutes a problemIn this paper modal analysis is made on the exhaust system of a passenger car. For estimation of the modal parameters two scenarios were used: Estimation using only the responses when excited by the engine during operation and classical input output modal analysis. The results from the two different methods are compared.When using the response measurements only to estimate the modal parameters different types of dedicated estimators for Operational Modal Analysis are used and compared
