摘要:
基于开放式有限元系统SiPESC.FEMS,构建了机翼流固耦合分析的程序框架。程序框架通过研发流固耦合界面数据交换模块来调用结构和流体分析功能.在流固耦合分析中采用高阶面元法对流体计算以获得飞行器机翼上各点处的压力系数。耦合界面交互采用径向基函数插值算法进行流固两相的载荷和位移的双向插值。进一步通过调用结构分析模块计算结构响应更新结构构型,实现机翼流固耦合整体流程分析。计算过程中各分析模块之间的数据传递均是基于大规模工程数据库SiPESC.ENGDBS来实现的。通过算例测试验证了在SiPESC平台上进行流固耦合分析的可行性。
Abstract:
Based on the open-style finite element system SiPESC.FEMS, the software framework which is able to perform fluid-structure coupling analysis of wings is built. The software framework has designed the fluid-structure coupling interface data exchange module to invoke the structure and fluid analysis functions. The method of fluid computation in fluid-structure coupling analysis is higher order panel method which can compute pressure coefficients of aircraft’s surface. The algorithm of radial basis functions approximations is adopted to conduct bidirectional interpolation of loads and displacements between fluid and structure. By using the structural analysis module to calculate the structural response and update the structural configuration, the overall flow of fluid-structure coupling analysis of wings is realized. The data transfer between SiPESC solid finite element computation module and process of fluid computation is implemented by large-scale engineering database SiPESC.ENGDBS. Feasibility of fluid-structure coupling analysis on SiPESC platform is verified by some numerical examples.
