Research overview:
We propse new SI measurement method in order to apply to thick structures. In this method, the entire vibration ditribution in structure is estimated by dyanamic analysis of finite element method with its partial surface ibration data, and using these analysis result, the entire SI ditribution can be obtained. The merits of this method are the followings. One is the only surface vibration data of structure is needed to measure, and another is that it is applicable for arbitary 3-D structures.
