摘　　要：结合我国自主研发的20k W斯特林太阳能热发电系统的聚光器镜面组件,通过比较几种不同的镜面组件排布方式,提出了3层多碟式排布方案。针对面积较大的中间层镜面组件,采用面向制造的设计方法,优化背板结构。在满足背板可成形性的基础上,通过在背板背面增加矩形空心型钢,提高了镜面组件的整体刚度。采用有限元模拟的方法对背板的可成形性进行了研究,通过调整合适的加强筋截面尺寸和摩擦系数,解决了背板成形时的破裂问题。模拟和试验表明背板在一套模具下可顺利成形。Combined with the concentrator mirror components of our country＇s self-developed 20kW stirling solar power system, three-layer multi-dish aligning scheme of mirror components is proposed by comparing with several different aligning schemes. By making use of the method of design for manufacturing, according to the larger area of mirror components, the structure of backplane is optimized. On the basis of formability of backplane, the stiffness of mirror components is improved by attaching rectangular hollow section profile. Appropriate stiffener section sizes and friction coefficient are choosen to avoid the fracture problem of backplane during the forming process by FEM. The results of simulation and test prove that the backplane can be formed successfully in one set mold.
