An optimization technique called shape-linked optimization, which is different from the traditional optimization method, is introduced in this paper. The research introduces an updated wing optimization design in an effort to adapt to continuous structure changes and shapes while optimizing for a lighter weight of the structure. The changing tendencies of the thickness of wing skins and the cross-section areas of the wing beams are fitted to continuous polynomial functions, whose coefficients are designed as variables, which is a different engineering approach from the size variants of the thickness and the area in the traditional optimization. The structural strength, stiffness, and stability are constraints. Firstly, this research unearths the significance of utilizing a modernized optimization process which alters the production of the traditional 12 or over 12 segment wing design and applies new approaches and methods with less variables that contribute to expedited design cycles, decreased engineering and manufacturing expenditures, and a lighter weight aircraft with lower operating costs than the traditional design for the operators. And then, this paper exemplifies and illustrates the validity of the above claims in a detailed and systematic approach by comparing traditional and modernized optimization applications with a two-beam wing. Finally, this paper also proves that the new optimized structure parameters are easier than the size optimization to process and manufacture.

机翼组件的全参数优化设计

介绍了一种不同于传统优化方法的形状链接优化方法。这项研究引入了一种更新的机翼优化设计,旨在适应连续的结构变化和形状,同时优化结构的重量。机翼蒙皮厚度和机翼横梁横截面积的变化趋势适合连续多项式函数,该函数的系数被设计为变量,这与厚度和面积的大小变化是不同的工程方法。传统优化。结构强度,刚度和稳定性是制约因素。首先,这项研究揭示了利用现代化的优化工艺改变传统的12段或12段以上机翼设计的生产并应用变量较少的新方法和新方法的重要性,这些新方法和新方法有助于加快设计周期,减少工程和制造费用,减轻重量重量轻的飞机,运营成本比传统设计更低。然后,本文通过将传统的和现代化的优化应用程序与两波束机翼进行比较,以详尽而系统的方式举例说明并说明了上述权利要求的有效性。最后,本文还证明,新的优化结构参数比尺寸优化更易于加工和制造。
