【 摘 要 】

When buying cars, consumers pay attention not only to the power and economy of the car, but also to its riding comfort. As an important index of ride comfort, car noise has been paid more and more attention. In order to achieve the goal of noise reduction, researchers and engineers have done a lot of research work on automobile noise control. Based on the finite element method, the internal model of acoustic material is applied to the coupling system composed of car body model and cabin model to study the noise reduction effect of acoustic material. Practice shows that the application of acoustic materials in automobile noise reduction not only has theoretical significance, but also is one of the important measures to effectively solve automobile noise.
