基于声学传递向量(ATV)法对声学贡献问题分析进行了分析和讨论;针对某型轿车建立了车内空腔的有限元和边界元模型,并将边界元方法与ATV法结合起来研究了车身板件声学贡献的特点和确定方法;在此基础上对车内噪声进行了分析与控制.%The issue of acoustic contribution is analyzed and discussed based on acoustic transfer vector (ATV) approach. Both finite element and boundary element models for the interior cavities of a car is set up, and by combining the boundary element method with ATV approach, the features and determining method of the body panels" acoustic contribution are studied; Based on this, the analysis and control of in-car noise are performed.
