Influence of Complex Distributed Stress on Structural Power Flow

doi:10.16183/j.cnki.jsjtu.2017.09.005

Abstract

Abstract: Based on the Kirchhoff plate theory, the orthogonality of specific order modes is used to derive the power flow equation of complex stressed structure, which can help to calculate the power flow of the structure with arbitrary stress distribution. The equation is validated by the numerical examples. Meanwhile, the influences of welding stress on a vibrating plate’s velocity, structural internal force and power flow are obtained. The results show that the influence of stress on power flow is more significant than velocity and internal force field. It should be taken it into account in actual engineering vibration prediction and reduction.

Key words: structural; stress; vibration; power flow
