| 摘 要： | 基于建立的模拟半梁式全金属x型号飞机机翼模型，用等刚度设计方法建立半梁式半复材、全复材的模拟x型号飞机机翼模型。用软件ABAQUS分别采用其中的三角形以及四边形壳单元计算全复合材料机翼、半复合材料机翼、全金属机翼在同种气动外形和载荷下的有限元分析，研究位移和应力的收敛情况。数值计算表明：位移收敛速度较快，应力收敛较慢，用不同类型单元和逐渐加密有限元网格对收敛判断是必要的。半复材机翼比全金属机翼减重35％左右，全复材机翼比全金属机翼减重接近50％。

| Abstract: | In this paper,a simulate model of a half-beam all-metal wing of XX model aircraft is created as the basis for establishing finite element models for half-composite or full-composite wings of equal stiffness.The full-composite wing,half-composite wing and all-metal wing of the same aerodynamic shape and load are modeled with the triangular and quadrilateral shell elements of ABAQUS for finite element analysis.The convergence rates of displacement and stress finite elements are also analyzed.Results show that... |
