ABSTRACT:
A method is provided for designing deformations that will achieve an optimum reduction in vibration related noise in an exhaust system component. The method entails defining an initial shape for an exhaust system component based on available space and exhaust flow characteristics. The shape is converted to a mesh having a plurality of interconnected grids. The mesh then is deformed to define an optimal theoretical configuration for the exhaust system component that will eliminate at least selected natural frequencies. The resulting shape then is converted to a plurality of small flat surfaces that intersect, and a point cloud is created from the array of small flat intersecting surfaces of the optimal theoretical exhaust system component. The point cloud is employed to smooth out intersecting surfaces and to achieve an optimal manufacturable configuration for the exhaust system component.
