| 摘 要： | 遵循静气弹问题中气动/结构网格之间的数据传递要求,引入了基于径向基函数的流固耦合界面数据传递方法,确定了紧支半径的选取原则,并编制相应的计算程序。以M6机翼为例,将不同径向基函数的插值精度及计算效率进行比较,结果表明体样条（Volume Spline）函数和C2函数具有良好的插值精度和计算效率。这两种流固耦合界面数据传递方法非常适用于工程应用。

| Abstract: | Following the requirements of data transfer between the fluid-structure girds in aeroelasticity,a method based on radial basis function is introduced.A principle about how to chose compact support radius and a coupling program is proposed.Taking M6 wing as a example,we compare different functions in accuracy and efficiency.It is turn out that volume spline function and compact radial function C2 show good performance in accuracy and efficiency.These two fluid-structure interaction functions are suitable for engineering application. |

| Keywords: | fluid-structure interaction radial basis function data transfer aeroelasticity |
