摘　　要：提出气动条带式喷丸成形方法成形大型复杂型面机翼壁板,根据壁板外形曲面曲率和厚度分布,采用"整体分条,单条分区"的方法对壁板进行条带式喷丸成形。通过基础试验确定了壁板喷丸工艺参数,利用特征优化映射方法获得了壁板板坯几何模型,采用预应力方法提高了条带喷丸成形变形量。上述技术均在ARJ21大型超临界机翼壁板上获得了工程应用。A method of aerodynamic banded shot peen forming is proposed to form large wing skin panels with complex profile. The panel is integral subdividing into bands and subregions in band to carry out shot peen forming according to the contour curvature and thickness distribution. The shot peen forming parameters are determined by fundamental experiments with panel specimens, the geometric model of panel blank is obtained with optimized feature mapping method, and the shot peen forming deformation amount is increased with prestress method. The above-mentioned banded shot peen forming method is applied in the large supercritical wing skin panels of ARJ21.
