摘　　要：对几何模型的不同建模方法直接影响到有限元计算的结果精度、计算时间等。基于一般计算机硬件限制,为了提高计算效率,可以尽可能地、合理地简化几何模型。文中对某试验用变压器的油箱和储油柜,分别建立3D实体和2D壳模型,利用有限元分析软件ANSYS Workbench进行地震加速度谱计算,并对以上2种模型的计算结果进行对比,对有限元模型简化方法提出了建议。The different modeling methods of geometric models directly affect the accuracy and computation time of finite element calculations.Based on general computer hardware limitations,geometric models can be simplified as much as possible to improve computational efficiency.This paper establishes a 3D solid and 2D shell model for the fuel tank and oil conservator of a test transformer.The finite element analysis software ANSYS Workbench is used to calculate the seismic acceleration spectrum.The calculation results of the above two models are compared.Suggestions are made for the simplified method of the finite element model.
