Abstract
本发明属于净成形精锻叶片锻造成形技术领域，具体涉及一种基于净成形精锻叶片锻造的型线扭角补偿方法及装置。方法包括：根据精锻叶片弦线角的三坐标检测数据，确定M个叶尖叶型An的弦线角θ′与理想叶型的弦线角θ的差值的平均值△θ；根据△θ确定对应需要补偿的叶尖叶型的扭角值△θ′，△θ′＝－k×△θ；根据△θ′确定截面A2至截面An‑1的扭角补偿值，基准截面A1扭角补偿值按0°计，叶顶截面An的扭角补偿值按△θ′计，其余截面按如下公式计算：式中:△θ′(Ax)为Ax截面的扭角补偿值；x为2至n‑1，Hx为截面Ax‑1与截面Ax之间的截面间距；以△θ′(Ax)将对应截面按积叠点进行旋转补偿，确定三维数模参数，加工模具进行生产。
