BIW Modal Analysis and Research Based on the NVH
Abstract:
The car body-in-white as the core research objects, NVH performance based on white body in finite element modeling and numerical modal analysis, this paper finds out the natural frequency of vibration may cause the BIW’s resonance. It indicates the direction to improve body-in-white NVH performance, local stiffness and further structural optimization through testing modal, stiffness analysis and NTF / VTF experiments to validate the numerical results of the modal analysis of the credibility and the body-in-white how much frequency or frequency band resonance peak caused by the body.
