摘要
飞机装配型架的设计在飞机的生产准备中占有很大比重。为缩短飞机的研制周期，在型架设计领域内采用CAD技术非常必要。本文简要介绍洪都航空集团河XCAD系统开发的指导思想及一些主要模块，包括型架常用标准件、通用件库、型架外形板（卡板）、骨架（框架）的参数化设计、型架元件空间角度计算、尺寸公差的查询与标注以及工程图绘制工作环境的设置等。
The design of aircraft assembling jig occupies too much work in the air-cluft production preparations. In order to shorten the aircraft development schedule, it isnecessary to adopt the CAD technique in the jig design field. This paper is to describe theguidance idea of FIXCAD system development and some main modules including the com-mon jig standard parts & universal - purpose parts database, jig contour - plate(clamp) &frame palumeterized design, jig element space angular calculation, dimension tolerance ad-visory & marking and setting of engineering dluwing plotting operational envilnnrnents, etc.
