摘要
把平板网架结构简化为空间桁架体系,利用大型数值仿真计算软件 ANSYS 对其进行模态分析。文中介绍了平板网架结构 ANSYS 分析的方法与相关命令流,讨论了质量分布模型对分析结果的影响,并采用拟夹层板法来验证了模态分析的正确性。
Based upon the space truss model,model analysis of double-layer grids is presented with large numerical simulated software ANSYS.In this paper,procedures and commands of ANSYS analysis are depicted.Moreover, influence of mass distribution model on calculated results is discussed.Finally,The accuracy of the calculated re- sults is verified by the analogy sandwich plate method.
