Abstract
This paper presents two proposals in TPA using finite element model: 1) technique in contribution analysis to the structure with manifold and continuous transfer paths, 2) visualization technique of the influence degree for the reduction of the response of the structure. The influence degree is newly defined by the result of the contribution analysis and assists analysts to obtain measures more efficiently. These two techniques let the analysts easy to understand the vibration transmission by the visualization. The application to an automotive body structure validates the effectiveness and usefulness of the proposed approach.
