【摘要】 为了提高有限元分析方法在复杂装备设计中的效率和质量,在深入研究现有计算机辅助工程软件的基础上,建立了平面三角形网格划分系统。该系统能实现异构的Ansys平台和Patran平台网格数据的导入;提供多种途径多层次的网格尺寸控制方法;实现面向多区域问题的Delaunay算法、推进波前法和映射算法混合应用。通过在航空发动机轴对称零部件的热固耦合分析中的应用,证明了所提方法的有效性。更多还原

【Abstract】 To improve efficiency and quality of finite element method in complicated assembly design,based on studies of several current Computer Aided Engineering(CAE) platforms,a triangle mesh generation system was established.In this system,isomeric mesh data from heterogeneous Ansys and Patran platform could be imported.Size control methods of mesh element were implemented from several aspects to generate size field information.Hybrid application of Advancing Front Technique(AFT) /Delauany/mapping algorithms for multi-area problem was realized.This system was applied in coupled thermo-solid analysis on axisymmetric components of aero-engine.Application results showed that the proposed method was effective.更多还原
