民机典型机翼结构的多层次制造成本模型研究

摘要

Wing structural design not only needs to meet the strength, stiffness and other mechanical requirements, the issue of manufacturing cost should also be considered. Based on a review on various cost should also be considered estimation models at home and aboard, it is found that costing methods based on historical weight estimations lack the direct coupling between cost and major design parameters, therefore inappropriate for use in the entire design process. To tackle this problem, a new multilevel cost model implemented within commonly used CAE tool is presented.%机翼的结构设计不仅要满足强度、刚度等力学性能要求,还要考虑制造成本因素.纵观国内外主要的成本估算模型,难以找到可以适用于设计全过程各个阶段的成本模型,同时基于历史数据的重量成本法的模型缺乏与主要设计参数的直接耦合,难以在整个设计过程中使用而基于CAE软件的多层次成本模型可以比较好地解决这个问题文中根据飞机不同设计阶段的特点,提出一种新的多层次成本模型的方法,并通过将成本模型直接与CATIA中的参数化模型相结合,建立多个涉及不同细节、又相互关联的递进的结构模型
