Research of Power Flow Boundary Element Method for Vibrational Analysis of One and Two Dimensional Structures
1차원 및 2차원 구조물의 진동해석을 위한 파워흐름경계요소법의 연구
Abstract
In this paper, Power Flow Boundary Element Method(PFBEM) has been developed for one and two dimensional noise and vibration problems in the medium to high frequency ranges. Green functions used for PFBEM are the fundamental solutions of energy governing equations. Both direct and indirect methods of PFBEM have been formulated and numerically applied to predict the vibrational energy density and intensity distributions of simple beams, rectangular plates and L-type plates.
