Vibration Power Flow Analysis of Ship Structures Using SEA Parameter(Coupling Loss Factor)
SEA 파라미터(연성손실계수)를 이용한 선박의 진동 파워흐름해석
Abstract
This paper proposes the new hybrid analysis of vibration in the medium to high frequency ranges including PFA and SEA concept. The core part of this method is the applications of coupling loss factor(CLF) instead of power transmission, reflection coefficients in boundary condition. This method shows very promising compared to the classical PFA for the various damping loss factors and wide ranges of frequencies. Besides this paper presents the applicable method in Power Flow Finite Element Method by forming the joint element matrix with CLF. These hybrid concepts are expected to improve SEA and PFA methods in vibration analysis.
