摘要：

The optimal design method of the truss structure in solar concentrator system is presented by hierarchy optimization strategy. First of all, the topology optimization model of the concentrator frame is established based on the method of evolutionary structure optimization (ESO). Next, according to the topology optimization of the frame structure, a feature line extraction method is presented to transform the topological optimization result into line unit. Then the truss section size is optimized based on the feature line extraction result. Finally, the optimization of the section size of the truss structure in the concentrator is completed. Taking the 38 kW dish-Stirling solar system as an example, a lightweight optimization design has been carried out for the truss structure in the concentrator system. The result shows that the weight of the single new truss is reduced by 34.4% when the new truss and the original truss has the same maximum deformation. This optimization strategy could provides fundamental for the lightweight design of truss structure. © 2020, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
