摘要
针对飞机产品设计过程中存在的多参数高度耦合问题,建立了产品设计关系网络图模型,给出了参数关联值的定义,提出了设计迭代控制方法,借助参数关联密度和关联深度,得出了最优设计路径的评价指标。并将该方法用于某飞机机翼的迭代设计过程中,获得了提高中央桁强度的最优设计迭代路径,极大地提高了设计效率。
Aiming at the problem caused by the highly coupled multi-parameters in aircraft design, firstly a network graph model of product design relationship is established, and the definition of the association values of parameters is studied; secondly, a method for design iteration control is proposed; and finally the evaluation objectives of the most optimal design path based on the density and depth of parameter association is obtained. This method has been used in a design iteration process of an aircraft wing, and the obtained optimal design iteration path of the central girder strength indicated the high enhancement in the term of design efficiency.
