摘　　要：本文对航天结构上使用的复合材料纺锤杆优化设计问题进行了研究。在结构层面,复合材料纺锤杆的截面沿轴向是变化的,在材料层面,杆件由各向异性的复合材料制作而成,因此,复合材料纺锤杆的优化设计相比传统材料杆存在更多的特点和难点。针对复合材料纺锤杆优化设计问题的特点和难点,提出了针对性的分区域优化模型,拓宽了优化设计的空间;建立了基于MATLAB和Ansys的优化设计方法,实现了复合材料纺锤杆的智能优化设计。优化结果表明,基于本文提出的优化设计模型和方法,纺锤杆较初始设计减重39.0%,较以往模型减重15.9%,证明了优化设计模型的优越性和优化设计方法的可行性。The optimization problem of composites spindle-shaped struts used in aerospace is studied in this paper.From the structural perspective,the cross-section of the spindle-shaped strut varies along the axial direction,and from the material perspective,the strut is made of anisotropic composites.Therefore,the optimization of composites spindle-shaped struts contains more characteristics and difficulties than traditional material struts.In view of these characteristics and difficulties,a targeted regional optimization model is proposed to expand the optimization design space.An optimization process based on MATLAB and Ansys is established to realize the intelligent optimization of composites spindle-shaped struts.The results show that,based on the regional optimization model proposed in this paper,the strut weight is reduced by 39.0%compared with the initial design and 15.9%compared with previous models,which proves the feasibility of the optimization process and the superiority of the optimization model.
