基于物理的能量最小法构造融合过渡曲面

Generating Blending Surface Based on Energy Minimization

提出了用基于物理的能量最小法构造四边域或n边域融合过渡曲面的方法,特别是用于解决四边域管状封闭非周期性曲面和其他曲面间的过渡问题,和任意n边域曲面和其他曲面间的融合问题。所提出的方法,只需给出边界法矢,将要求通过的约束线作为位置约束,即可构造G1连续的满足工程要求的融合过渡曲面。该融合过渡曲面的过渡区域较易控制,并且能满足一些工程约束。详细讨论了基于物理的能量最小法构造过渡曲面的原理及求解方法,并给出了飞行器的翼身融合过渡实例。

A method of generating blending surface based on energy minimization is presented in this paper. Especially, this method is able to solve the problems to generate blending surface between closed nonperiodic tube-like surface and other surface and generate blending surface between n-sided surface and other surfaces. The region of the blending surface generated by this method can be controlled easily. And the blending surface can meet some engineering constraints. This paper discussed the principle and solution method about generating blending surface based on physical energy minimization in detailed. An example, blending surfaces between the aerofoil and the body of aerocraft, is shown.
