基于COMSOL Multiphysics的格栅拱架模型力学性能研究

通过在COMSOL Multiphysics建模下构建格栅拱架模型,运用其固体力学模块中的屈曲分析和稳态研究功能,对模型的承载能力和变形特性进行了计算和仿真研究,分析得到拱圈和格栅有应力传递现象、下拱圈两翼发生S状变形的结论。

The grid arch frame model is built under the COMSOL Multiphysics modeling, and by adopting the buckling analysis and the steady-state research function of its solid mechanics module, the load-carrying capacity and deformation characteristics of the model are calculated and simulated. The results of stress transfer in the arch ring and grid and S-shaped deformation of the lower arch ring are obtained.
