摘　　要：基于通用有限元软件ANSYS建立了某大型铝电解槽结构的三维实体模型和热应力场耦合分析的有限元模型.考虑材料非线性和接触非线性的基础上对电解槽结构强度进行了仿真计算,给出了槽壳和摇篮架的应力、应变云图,分析了电解槽结构的变形规律,并提出了结构优化的途径.以槽壳近似弹性体为目标,对不同组合载荷工况进行了反算,得出与实际更接近的荷载条件.The three-dimensional thermo-electric solid and finite clement model of a great aluminum reduction cell was built based on general finite analytic software ANSYS. Simulation computing was processed with the double nonlinear affection of elasto-plastic material properties and contact problem taken into account, the stress contours and strain contours of cell wall and cradle rack were plotted, the deform law of the aluminum reduction cell＇s structure was analyzed, and some optimal measures were proposed for structure design. Reverse calculation was carried out under different load conditions on the assumption that the aluminum reduction cell was a elasticity body, and the best loading condition was achieved, which would offer a rapid and available research means for further design and reconstruct of an aluminum reduction cell.
