机翼翼盒装配间隙精密补偿研究

Research on Active Compensation for Assembly Gap of Aircraft Wing Box

在机翼翼盒的装配中多采用被动补偿的方式消除壁板和骨架的装配间隙,装配间隙难于精确测量且补偿工艺复杂,由此开展机翼翼盒装配间隙精密补偿方法的工艺性研究,通过对精密补偿技术中配合面精确测量和补偿余量精加工去除工艺等关键技术的分析,可实现机翼翼盒骨架与壁板的精密补偿无间隙装配,从而提高飞机机翼翼盒的整体装配水平。

Passive compensation is mainly used in the assembly of wing box, which is helpful to eliminate the assembly gap between the panel and skeleton. But, to measure the assembly gap accurately is difficult and the compensation process is complicated. Thus the process study of active compensation for the assembly gap of the wing box is carried out. By analyzing key technologies of active compensation, such as precision measurement of contact surface and finishing removal process of compensation margin, active compensation assembly without gaps of wing box skeleton and panel can be achieved, so as to improve the assembly level of aircraft wing box.
