Determination of Contribution Panels of Vehicle’s Interior Noise Using NTF, ODS and PFP
摘要
Abstract
The noise transfer function (NTF) model of a bus body was established to evaluate the peak frequencies of the interior noise. Then, the large deformation of the bus body model was analyzed at the peak frequencies of the interior noise based on the theory of the operational deflection shape (ODS). The positions of the large deformation were defined as the noise contribution panels. The acoustic contributions of these panels to the interior noise level were estimated according to the analysis of the participation factor panel (PFP). The results provide valuable guidelines for the determination of contribution panels of vehicle’s interior noise.关键词
