In order to improve the accuracy of large-size aircraft ribs assembly location, reduce the deformation of the assembly and finally meet the requirements of the deviation of the ribs spacing in the wing box assembly process, based on the analysis of the assembly positioning requirements and the position uncertainty of the large-size ribs assembly, a kind of rigid assembling technology of dot matrix was proposed. A new set of rigid lattice enhancing tool was designed based on the deformation analysis, which realized the large-size rib-shaped positioning and the multi-degree-of-freedom adjustment of the positioner. It reduces the deformation of the ribs and ensures the ribs spacing, which is of guiding value for the actual assembly of the large-size aircraft ribs.%为了提高大尺寸飞机翼肋装配位置准确度、减小装配变形并最终满足机翼翼盒装配过程中翼肋间距偏差要求,在深入分析大尺寸翼肋装配定位要求和位置不确定性的基础上,提出了一种点阵刚性增强装配技术,结合变形分析设计了一套全新的点阵刚性增强工装,实现了大尺寸翼肋保型定位和定位器多自由度调整、减小了翼肋变形、保证了翼肋间距,对于大尺寸飞机翼肋的实际装配有一定的指导价值.
