摘　　要：金属幕墙广泛用于大型建筑的外墙装饰,其中曲面造型的大型建筑外表大多由二次曲面相贯或拼合而成。二次曲面属于不可展曲面,用于金属幕墙的平面金属板材经冲压而成曲面时会产生褶皱。由于曲面造型的曲率不对称性,褶皱的分布并不均匀。提出一种褶皱优化的横向推位算法,使得曲面冲压成型时产生的褶皱可以均匀分布,解决了曲面冲压成型的准确性要求。Metallic curtain wall is widely used in external decoration of large construction; the surface modeling of large construction appearance is mostly composed of hyperboloid. The hyperboloid,as undevelopable surface,will cause the creases while stamped into surface form a flat sheet metal. However,the distribution of creases is not uniform because of the curvature asymmetry. A transverse displacement algorithm of optimized crease is proposed in this paper to enable uniform distribution of crease while the surface is stamped to form a flat sheet metal,which meets the requirements of form accuracy in surface stamping of hyperboloid metallic curtain wall.
