摘要
为减少槽式聚光镜结构的用钢量,选取聚光镜拉翅、主三角桁架的截面尺寸及拉索初拉力为优化参数,以镜面变形与构件应力为约束条件,采用均匀设计法对聚光镜结构在最不利工况下进行优化设计;并通过有限元分析对优化结果进行检验。研究结果表明,均匀设计方法可以用于聚光镜结构的优化,在满足结构变形的控制条件下聚光镜的用钢量可减少10.3%,优化结果可为槽式聚光镜结构初步设计提供参考方案。
In order to reduce the consumption of steel, taking the wing＇s rod sizes, triangular truss＇s rod sizes and the initial tension of cable as the optimization parameters, and considering mirror distortion and component stress as the constraint conditions, uniform design method was used to optimize the condense mirror structure under the worst operating situation; And finite element analysis was adopted to test the optimization results. The results show that uniform design method can be used to optimize the condense mirror structure. The steel quantity of condense mirror meeting the control conditions of structural deformation can be saved by 10.3%, and the optimization results can provide reference schemes for preliminary structural design.
