轿车车内空腔声学模态

Acoustic Modality of Car Cavity

阐述了轿车车内空腔声学模态 ,为了获取车内空腔的声学共鸣频率 ,提出了一种空腔声学模态试验方法 .并对实车的声学模态试验结果与该车车内声学模态的有限元计算结果进行了比较 。

This topic introduces the acoustic modality of car cavity,presents a kind of testing method to acquire the modal frequency and compares the test result with the result of Finite Element Analysis (FEA).It provides the reference to research low frequency noise inside a car.
