Method for mapping structural pneumatic mesh force to finite element nodal force

The invention belongs to the technical field of mapping from structure pneumatic grid force to finite element nodal force, and particularly relates to a method for mapping from structure pneumatic grid force to finite element nodal force, which comprises the following steps: constructing a structure three-dimensional pneumatic model; constructing a structural finite element model; distributing aerodynamic force on grids of the three-dimensional aerodynamic model of the structure to nodes of the finite element model of the structure; the node force on the structure finite element model is optimized by taking aerodynamic force on a three-dimensional aerodynamic model grid, total force conservation and total moment conservation among node force on the structure finite element model as constraint conditions and taking minimum virtual work deviation as an optimization target. 本申请属于结构气动网格力到有限元节点力的映射技术领域，具体涉及一种结构气动网格力到有限元节点力的映射方法，包括：构建结构三维气动模型；构建结构有限元模型；将结构三维气动模型网格上气动力分配到结构有限元模型的节点上；以三维气动模型网格上气动力、结构有限元模型上节点力间总力守恒、总力
