针对机翼翼型不光顺的工程问题,提出一种基于数据列离散曲率理想值进行数据筛选及处理的曲线光顺方法。离散曲率理想数列通过均匀B样条改进的最小二乘方法计算得到。算例表明,本文所提方法便于能够有效光顺曲线点列,且计算精度及计算范围可依需求定制。
Aiming at the engineering problems of wing airfoil, this paper presents a curve smoothing method based on ideal value of discrete curvature of data column for data selection and processing. The ideal sequence of discrete curvatures is calculated by the least squares method of uniform B-spline refinement. The example shows that the method proposed in this paper can facilitate the smooth curve point column, and the calculation accuracy and calculation range can be customized according to the requirements.
