| 摘 要： | 该文在径向基函数(radial basis function, RBF)及其插值函数研究基础上，构建了基于RBF插值的流固耦合信息传递模型，进一步通过程序编制，在同济大学空间结构自动分析与设计软件—AADS系统中实现了对任一时间步上的流固交互作用分析，并得到与ADINA软件非常吻合的计算结果。算例分析表明:径向基函数可作为一种有效的界面信息传递方法应用于对三维流固耦合问题的研究。

| Abstract: | Based on the study of RBF and its interpolating function,an information transfer model of a fluid-structure interaction(FSI) is build using RBF interpolating function.By program development,the fluid structure interaction analysis of each time step is performed on the Space Structure Automatic Analysis and Design System(AADS) of Tongji University,and the result of AADS is very close to the result of ADNIA software.The example analysis shows that RBF can be taken as an effective data exchange method and used to analyze a 3D FSI problem. |
