摘要
本文讨论车身板件振动声学贡献的计算机模拟研究方法。以桑塔那2000型轿车为实例建立无吸声材料和有吸声材料的结构-声学模型,使用ANSYS有限元分析软件计算车身板件在给定频率下振动引起的车内声压,进而求得板件的声学贡献。
This paper presents a computer simulation on acoustic contribution of vibrating body panels. The structure-acoustic coupled models of Santana 2000 are built both with and without absorption material, and ANSYS finite element analysis software is used to calculate interior acoustic pressure due to panels vibration under specific frequency, then the acoustic contribution of panel is evaluated.
