为分析约旦次临界装置台架是否具有承受静载荷的能力,在设计输入的结构、载荷和规范要求的条件下,使用有限元分析软件ANSYS进行静力分析。台架属于4条支腿支撑的平台结构,考虑到结构多为钢板和钢管,有限元模型(图1)统一采用8节点三维壳单元SHELL93,从而合理有效地简化了计算模型。实验人员的重压均按等效压力保守地施加在平台和台阶上,为减少程
In order to analyze whether the Jordan subcritical stand has the capability of bearing static load, static analysis is carried out using the finite element analysis software ANSYS under the design input structure, load and specification requirements. The platform is a 4-leg platform structure. Considering that the structure is mostly steel plate and steel pipe, the finite element model (Figure 1) adopts the 8-node three-dimensional shell element SHELL93, which simplifies the calculation model reasonably and effectively. The weight of the experimenter are conservatively applied to the platform and the steps according to the equivalent pressure, in order to reduce the distance
