摘要:
针对单层球形网壳进行结构设计.以网壳承受的风载为设计载荷,利用FLUENT软件得到网壳表面风压分布载荷.采用单向流固耦合(FSI)技术,将计算得到的表面风压施加到网壳结构分析模型上.通过结构分析的非线性计算,得到网壳在风载条件下的应力分布及变形.以网壳梁截面尺寸最小为优化目标,得到满足设计指标要求的梁截面尺寸.通过现场实验,得到网壳节点位移载荷曲线,在相同条件下,将实验结果与仿真模型进行对比,验证了网壳结构模型的正确性.
Abstract:
This paper studies the structural design of the single-layer spherical shell. with the wind loads ofshell bearing for design load,using FLUENT software to get the shell surface wind pressure distribution.Thecalculated surface wind pressure is applied to the shell structural analysis model,with unidirectional fluid-solidcoupling ( FSl) technology. Through the nonlinear calculation of structural analysis,we the stress distributionand deformation of shell under the wind load conditions. With minimizing beam section size of shell as optimi-zation goal,we obtained the size of beam section which satisfies the design requirements. Through field tests ,we got the shell node displacement load curve,and compared the results of the experiment with simulationcurves under the same conditions to verify the correctness of the shell structures model.
