Abstract

Structure born noise and air born noise are two basic noise sources of a vehicle. Structure born noise, which is mainly determined by the body structure, takes an important role in NVH performance of a vehicle. The mechanism of structure born noise is that the vibration coming from external excitation force (engine, road etc.) is transferred to body by structure parts, and then arose the body vibration. The objective of this chapter is to explore the mechanism of vibration and noise transfer of a trimmed body, introduce the factors that influence the noise transfer function (NTF), and take two examples to explore the methods and give a guidance to reduce noise transfer function (NTF) of a body.
