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。

Abstract: 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.
