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。 Following the data transfer requirements of aerodynamic / structural grids in the static gas bomb problem, the data transfer method based on radial basis function is introduced to determine the radius of clamped branch and the corresponding calculation program is compiled. Taking the M6 ​​wing as an example, the interpolation accuracy and computational efficiency of different radial basis functions are compared. The results show that Volume Spline function and C2 function have good interpolation accuracy and computational efficiency. These two fluid-structure interface data transfer methods are ideal for engineering applications.
