飞机装配过程数字化测量技术

Digital Measuring Technique in Aircraft Assembly

自20世纪以来,飞机装配过程中的测量检测技术经历了从"定性检测、事后检验"到"定量测量、实时跟踪"的转变。随着飞机装配向智能化迈进,数字化测量技术已经成为飞机装配过程的重要因素,并不断向"智能测量、反馈控制"的目标发展。本文首先回顾了飞机装配过程中测量检测方法从模拟量到数字量演变的4个阶段。随后,根据数字化测量技术的基本原理和测量目标,从点位坐标测量、形状特征测量和曲面外形测量3大类对当前飞机产品装配过程中主要应用的数字化测量技术进行了归纳总结。

Since the 20 th century, measuring technique in aircraft assembly procedure has been improved from qualitative and back test to quantitative and tracking measuring. Due to the development of intelligentization in aircraft assembly and consequently requirements in measuring, digital measuring technique becomes an essential factors in assembly procedure and are now stepping forward to intelligent measuring and feedback control. Four stages of measuring experienced in aircraft assembly are reviewed in this paper. Most of the measuring technique used in current aircraft assembly procedure are classified based on a proposed classification criterion, which includes point coordinates measuring, shape characteristics measuring and surface profile measuring.
