Optimization of Automotive Engine-cooling Fan Noise Using Response Surface Method
반응면 기법을 이용한 자동차 엔진 냉각팬의 저소음설계
Abstract
Response surface method is employed in optimizing the acoustic performance of automotive engine-cooling axial fans. The effects of modifications in blade geometry on noise reduction are investigated. Taking the far-field noise level as the objective, a quadratic response surface is constructed utilizing D-Optimality condition as the candidate-points selection criteria. It is shown that the quadratic model exhibits an excellent fitting capability resulting in the blade design with low far-field noise level.
