Abstract
This paper describes a proposal of techniques to analyze transmission of vibration among the parts or components of an automotive body structure using Transfer Path Analysis (TPA) [1].
TPA has not been applied to automotive body structure itself. One of the reasons is troublesome processes on the application to be treated with a lot of transfer functions and transmitted forces at the conjunctions which are complexly assembled with many adjacent nodes. Therefore it would be difficult to detect highly contributed parts or components in the structure.
Difficulties were resolved by introduction of a proper coordinate transformation of analytical degree of freedom (DOF) at the cross-section of parts or components in this study. These describe the transmission of vibration using physical aspects of vibration transmission theories familiar to engineers like those of beam or shell.
Contribution analysis of vibration was carried out for its upper side and under side of the body structure. Its usefulness was verified by this application with a couple of practical techniques.
