基于飞机产品结构更改的装配工装变型设计方法

 飞机研制过程中的频繁设计更改活动是造成装配工装设计修改工作量大、设计质量难以保证等问题的主要原因。为此，运用公理设计原理描述了装配工装设计问题，提出了一种基于飞机产品结构更改的装配工装变型设计模型。将数字化标准工装与工装概念几何作为控制几何，通过主几何层、源控制几何层、衍生控制几何层、工装部件层和工装设计基础库层之间自顶向下和自底而上相结合的综合运算实现装配工装变型设计，提高了装配工装设计对飞机产品结构更改的快速响应和应变能力。开发的变型设计工具集应用于飞机方向舵装配型架设计，避免了装配工装大范围设计迭代，有效提高了设计更改效率。

Variant Design Method for Assembly Tooling Design Based on Aircraft Product Structure Change

In the course of aircraft development, frequent aircraft design changes are the main factor which results in amendment of assembly tooling. In this article, assembly tooling design is described by the axiomatic design theory, and a variant method for assembly tooling design based on aircraft product structure change is presented. In this model, digital master tooling and tooling conception geometry are used as control geometry, and the model of assembly tooling variant design is created by top-down and bott...
