摘要
应用有限元方法对桁架式天线骨架结构进行分析,在关注区域建立了模型计算准确的应力分布。针对切割边界通过多自由度单元的子模型,提出了边界位移计算方法。对结构中部分参数结合结构分析进行优化设计和灵敏度分析,并对优化结果进行圆整。对于桁架结构设计与分析具有指导意义。
Analyze truss antenna framework structure with finite element method and establish sub-model to compute the stress distribution of the speecial part. In allusion to the sub - model of which incision boundary via multi - degree freedom element, this paper puts forward the method of computing boundary displacement. Optimizing and rounding off some parameters of the structure based on sensitivity. It is instructional to the design and analysis truss structure.
