轿车车身声灵敏度的分析

An Analysis of the Vibro-Acoustic Transfer Function for Vehicle Body

讨论对于无骨架式结构的车身声灵敏度和加振点传导性之间的理论关系,在论文加振试验时,理论功率公式预测车内声灵敏度和加振点传导性是有比例关系的。激振试验结果表明:在车身声灵敏度和加振点传导性之间好的相关关系应验证理论功率公式。

This paper discusses a theoretical relationship between a vibro-acoustic transfer function(TF)and a driving point conductance for a monocoque vehicle body Theoretical power equations during the excitation sest predict the driving-point conductance to be proportional to a sound pressure in the interiou room Excitation test trsults show that a good correlation between the vibro acoustic TF and the driving point conductance validates the theoretical power equations.
