基于 RBF 径向基函数建立了多块对接网格块顶点运动模式，进一步耦合 Delaunay 图映射建立网格变形技术；利用基准网格的稀疏序列节点以及区域顶点建立 Delaunay 四面体映射单元，利用 RBF 技术操作区域顶点运动，使映射单元进行变形，从而应用映射关系实现网格变形；针对某型支线客机进行了型架外形设计，并进一步进行对型架外形进行静气动弹性计算与设计巡航外形对比，验证了所建立的型架外形设计方法的正确性；静气动弹性计算中，通过建立共用的“映射曲面”，实现 CFD/CSD 数据高效交换。

The vetex deformation pattern of multi-block grids is developed based on RBF technique cou-pling with Delaunay graphic mapping to establishe grid deformation platform.The Delaunay cell is generated using the grid sparse points and block vetexs.When aerodynamic configuration deforms,the block vetex will be moved by RBF technique and the Delaunay cells will be deformed,consequently,the mapping relation could be obtained to realize grid deformation.A certain lateral aerobus is taken as an typical example,jig shape is proposed firstly,static aeroelastic analysis is processed then to get the cruise shape of jig configura-tion,and the comparison with cruise design shape is investigated.The results show that the correction of jig shape design method established in this paper is validated.On the other hand,the “mapping surface”can be used to realized CFD/CSD data transformation effectively.
