新型电解槽摇篮架受力变形分析

Force and Deformation Analysis of New Electrolytic Cell Cradle

本文采用ANSYS有限元分析软件,建立了老式摇篮架和新型预应力摇篮架的空间模型。采用实体力筋法来模拟预应力钢结构,预应力的模拟采用降温法。在分析过程中考虑了结构的材料非线性和几何非线性。对比分析了新型预应力摇篮架与传统摇篮架的受力性能、受力变形规律以及屈服荷载等。结果表明,通过施加预应力改变了原有的应力分布,结构整体内力分布趋于均匀,特别是45度斜向肋板上的拉应力得到明显改善,从而提高了构件的屈服荷载。

In this paper,large-scale ANSYS finite element software is used to establish the spatial models of the old-fashioned cradle and new pre-stressed cradle.Physical reinforcement method is used to simulate pre-stressed steel structure,and the pre-stressing force is simulated by cooling method.Both material nonlinearity and geometric nonlinearity are considered in the analysis.Comparative analysis of the mechanical performance,deformation regulation and yield load are made.The results show that the deformation amplitude of the pre-stressed cradle is changed,especially the tensile stress of 45-degree diagonal rib panel significantly improved,which can improve the yield load of the component.
