建立了网格结构的轴压有限元模型;利用ANSYS的APDL语言编写了网格结构稳定性分析的优化分析程序,并利用该程序分析了网格形状、筋截面形状对网格结构稳定性的影响;结果表明:网格形状为正三角形时,网格结构的稳定性最好;对于正三角形圆柱网格结构,在筋截面面积一定的条件下,筋截面高宽比为3:2时网格结构的稳定性最好。
The finite element model of the axial compression of the grid structure was established. The APDL language of ANSYS was used to compile the optimization analysis program of the stability analysis of the grid structure. The program was used to analyze the stability of the grid structure and the section shape of the grid The results show that the mesh structure has the best stability when the mesh shape is a regular triangle. For the regular triangle cylindrical mesh structure, when the section area of tendon is constant, the aspect ratio of the section is 3: 2 The lattice structure of the best stability.
