Abstract
This paper is concerned with the localization of structural forces acting in 2D plate at medium and high frequency ranges, through an inverse method based on energy quantities. An energy-based method, called simplified energy method (MES), has already been proposed to predict the energy density field repartition for structural–acoustic problems in mid- and high-frequency ranges. In order to illustrate but also to present one of the applications of this method, this paper presents a formulation to solve inverse structural problems. The main novelty of this paper is to localize the vibration sources in plates, thanks to experimental data of energy densities. The injected forces localization was obtained in the mid–high-frequency range. Experimental investigation was performed to test the validity of the presented technique using different positions of the shaker and measurement points. The experimental results show that the IMES method has an excellent performance in localizing the input forces.
