Abstract
Radiated noise from various components is of increasing concern for today's automotive manufacturers. Traditionally, this analysis was usually performed with Boundary Element Method (BEM) software. Unfortunately, there is no sensitivity or optimization capability within any known BEM code. This paper addresses the problem by describing the software developed by CDH, i.e., OPT and VAO, which combine the structural FEM analysis and optimization with BEM analysis such that one can perform analysis and optimization very quickly and efficiently. A sample air cleaner problem is described which illustrates the minimization of radiated noise at a predefined far-field positions.
