摘要

摘要: 在流体-结构联合分析过程中，获得流体网格计算结果后需要通过合适的数据传递方法将节点载荷映射到结构网格上.为了满足复杂曲面上节点力的传递精度要求，提出基于临界二面角判据和最大/最小影响半径的搜索算法，完成曲面上插值区域的判定.采用基于最小势能原理的三维节点力插值方法完成节点力在两套计算网格之间的数据传递，并通过数值算例验证了传递前后载荷分布、合力、合力矩的一致性

Abstract: In the process of fluid-structure coupling analysis, it is necessary to use appropriate data transfer method to map the node load onto the structural grid. To meet the accuracy requirements of nodal force transfer on complex surfaces, a search algorithm based on the critical dihedral angle criterion and the maximum/minimum influence radius was proposed to determine the interpolation area on the surface. A 3D node force interpolation method based on the principle of minimum potential energy was used to transfer node force data between 2 sets of calculation grids, the consistency of load distributions, resultant forces, and resultant moments after transfer was verified through numerical examples.
