Modal Analysis on an Exhaust Manifold to define a Catalyst FE-model

Faurecia Exhaust Systems AB develops and manufactures exhaust manifolds for the car industry. In the developing process the FE-models are one of the main tools and they are becoming more and more important in the automotive development. In the tough competition between the manufacturers, the demands for fast development require good FE-models both from the manufacturers and their subcontractors.The main goal of this thesis is to update an existing FE-model of a close coupled exhaust manifold and look at the catalyst to investigate the behavior of the catalytic converter and suggest a way to model the monolith.

The thesis combines analytical calculations with experimental measurements. By the use of modal theory, an analytical model is updated to resemble the experimental data.
