北京奥运会自行车馆原铸钢球铰支座数值分析

Finite element analysis of original cast steel spherical node of cycling gymnasium for Beijing Olympic Game

对北京奥运会老山自行车馆原铸钢球铰支座节点进行非线性弹塑性有限元分析,通过分析该节点在两种控制工况下的应力、变形状态证明该节点具有足够的承载能力以及转动能力,为该节点在工程中的使用提供了理论依据。

Nonlinear FEM numerical analysis of the cast steel spherical support node of cycling gymnasium for Beijing Olympic Game was carried out. Stress and deformation under two control cases were obtained through the finite dement analysis. Those results prove that the node have enough bearing capacity and rotating capacity which can be the theoretical warrant for the project.
