| 摘 要： | 根据界面能量守恒原理,将紧支径向基函数(compactly supported radial basis function,CRBF)引入流固交互作用分析领域,提出了基于CRBF插值的流固交互界面数据传递(CRBF/FSI).推导了界面位移传递矩阵H,并根据CRBF/FSI算法编制了相应的界面信息传递的计算程序.以三维交互界面的位移信息传递为例,将数值计算结果和解析解进行了对比分析,结果表明,CRBF/FSI算法计算效率高,计算结果准确,是一种适合处理大型复杂交互界面的流固信息传递方法,具有良好的工程应用前景. |

| Abstract: | Based on principle of conservation of energy,a method adopting compactly supported radial basis function(CRBF) is proposed to perform fluid-structure interaction(FSI) analysis.The displacement transfer matrix H is deduced and a corresponding program by CRBF/FSI algorithm is developed.Example of displacement exchange with 3D interface is studied.The numerical solution by CRBF/FSI method is compared with analytical solution.The result shows that CRBF/FSI method is efficient and accurate.It is suitable for FSI... |
| Keywords: | fluid-structure interaction data exchange compactly supported radial based function energy conservation |
