动态风载荷作用下大型集装箱船桥翼结构响应分析

Response analysis of large container ship bridge wing structures under dynamic wind loads

    摘要
  • 摘要:
    目的 旨在研究大型集装箱船桥翼结构设计过程中风载荷对桥翼结构安全的影响。
    方法 首先，研究不同垂向位置处动态风载荷的变化规律，提出动态非线性风载荷的施加方法；然后，采用ABAQUS软件对桥翼结构非线性有限元模型进行求解，获得动态风载荷作用下结构的应力和变形结果；最后，分析多载荷对结构响应的协同影响，并与静态风载荷结构强度计算结果进行对比，探究计及风载荷的动态效应对上层建筑结构响应的影响。
    结果 结果表明，风载荷动态效应对桥翼结构影响显著，会引起桥翼周期性晃动，使其在多载荷联合作用下产生显著的结构周期性响应。
    结论 研究成果可为进一步认识和考虑风荷载在结构设计中的作用提供重要参考。

     

    Abstract:
    Objectives  The aim of this paper is to study the influence of wind load on the safety of large container ship bridge wing structure.
    Methods Investigating the variation patterns of dynamic wind loads at different vertical positions, proposing a method for applying dynamic nonlinear wind loads, utilizing ABAQUS software to solve the nonlinear finite element model of the bridge wing structure, obtaining stress and deformation results of the structure under dynamic wind load, analyzing the synergistic effects of multiple loads on structural response, comparing them with the results of static wind load structural strength calculations, and exploring the impact of dynamic wind load effects on the response of upper building structures.
    Results The results indicate that the dynamic effects of wind loads significantly affect the bridge wing structure, causing periodic oscillations of the bridge wing and leading to significant structural periodic responses under the combined action of multiple loads.
    Conclusions The research findings can provide important references for further understanding and considering the role of wind loads in structural design.
