Abstract
Structural intensity measurement of a two-dimensional vibrational field is investigated numeri-cally and experimentally. A method that uses five accelerometers (5-point method) and a wave decomposition method are discussed. First, the error of the intensity measurement using the 5-point method is numerically discussed. Second, the wave decomposition method in atwo-dimensional field is applied to determine the vibrational field. The effectiveness of the wave decomposition method is numerically presented. Furthermore, these two methods are investigated experimentally. As a result, the structural intensity can be measured practically with high precision and the localization of source is possible using these methods. A technique for estimating the propagating power by measuring at a few points is also shown.
