摘要
本文介绍了汽车车身结构振动和乘座室空腔内部噪声的模态分析方法,并利用声-固耦合理论对车身结构振动与车内噪声之间的耦合关系进行了研究,为降低由结构振动所引起的车内低频噪声提供了结构修改和声学修改的措施。
This paper introduces the model analysis method of automobile body structure vibration and passenger compartment cavity noise, and uses structure-acoustic couplings theory to study the interaction between body structure vibration and interior noise, and finally provides the structural and acoustic modification methods for reducing interior low-frequency noise caused by body structure vibration.
