摘要
采用双三次Coons曲面片能较方便地拼合构造复杂工程曲面.Coons曲面片的划分可依据具体工程曲面的曲率半径进行.通过Coons曲面方程,考虑到角点切矢、角点扭矢对Coons曲面片边界形状与内部形状的影响,可构造出复杂工程曲面的数学模型,从而实现曲面片的相对光滑连接.
Complex engineering surface can be constructed by double cubic Coons surface.Division of Coons surface is based on the curvature radius of concrete engineering surface.Corner position tangential vector and corner twisting vector affect Coons surface patchess edge shape and inner shape is consided,math mode of complex engineering surface can be constructed,therefore,relative smooth connect of surface patch should be realisted.
