摘要
基于离散Coons曲面形状控制方法的研究,以第1类Coons曲面为例,对连续Coons曲面的形状控制方法进行了研究。提出了在固定边界条件下通过改变Coons曲面的混合函数来使曲面变形,并达到预期变形目的的方法,并指出混合函数对Coons曲面形状的影响要受到包括边界曲线在内的边界条件的制约,缺乏必要的边界条件就无法仅凭混合函数来达到所需的变形。
Based on the research of shape control methods of discrete Coons surfaces, the shape control method of continuous Coons surfaces using only blending functions is presented, while taking the first type blended Coons surface as an example. The method enables shape adjustment to the surfaces with boundary conditions unchanged. The deformation effect of this method is restricted by boundary conditions. Without proper boundary conditions the expected deformation would be impossible.
