水中管道悬跨节段涡激力下的动力响应分析
Dynamic Response Analysis of Vortex-Induced Vibration of Suspended Section of Submerged Floating Pipeline
摘要
Abstract
The suspended section of submerged floating pipeline is vortex-induced vibration under the effect of currents waves,which is main factor of tend to increase stress numerical,instability and service life of the pipeline.The simplified to beam and calculation model for suspended section of submerged floating tunnel is presented,on the basis of considering fluid-structure interaction,dynamic response equa tion is established.With the aid of ANSYS software,the finite element calculation model of the suspended section of the submerged floating pipeline is established and analysis of different modal order,suspended span length and pipeline water depth influence on dynamic response of pipeline.The results show that the first order modal is bigger influence on the vibration displacement;Pipeline vibration displacement in creased with the increase of suspended span section length gradually increase,decreases gradually with the increase of pipeline in the depth of the water.Study results for submerged floating pipeline safety monitoring and design of the suspended span section provides scientific theory basis.关键词
