摘　　要：基于HyperMesh建立的飞机的整体机翼有限元模型,并对整体模型进行了有效性校验;将实测的机翼载荷通过分载转换成有限元模型的节点载荷,并通过分载前后合力、合力矩的校核验证了分载方法的正确性;在对整体模型边界条件和工况载荷进行了处理后,开展了典型工况载荷下整体机翼结构的强度分析,得到主承力部件的应力分布,对危险部位进行重点研究。对以后工程研究提供了新的分载方式,对强度分析和结构优化垫定理论基础。The finite element model of the whole wing of a certain aircraft is established based on the HyperMesh,and the effectiveness of the whole model is verified in this paper.The measured wing load is converted into the node load of the finite element model through partial load,and the validity of this method is verified by checking the joint force and the joint force moment before and after load separation.After the whole model boundary condition and working condition load are treated,the strength analysis of the whole wing structure under this load is carried out,then the stress distribution of the main components is obtained;the dangerous parts are analyzed emphatically.It provides a new load sharing method for future engineering research,and lays the theoretical foundation for strength analysis and structural optimization.
