CAE-based procedure for the acoustic optimization of gaskets

Covers of combustion engines are often dominant noise sources. The NVH optimization of such structures is usually carried out on single components. These structures may exhibit unwanted noise emissions when combined into the entire powertrain structure. Possible acoustical interactions due to the dynamic transfer behavior of the gasket systems are neglected. The Institute for Combustion Engines of Aachen Technical University under the direction of Prof. S. Pischinger developed a method which allows to simulate and optimize the structure borne noise transfer of elastomeric gaskets.
