| 摘 要： | 以B747-400为例,考虑大型飞机复杂起落架构型和多轮荷载的作用特点,基于ABAQUS软件建立了多层复杂结构体系的三维有限元分析模型。应用该模型,计算了多轮荷载不同组合作用下加铺层的应力和变形,揭示了道面结构的力学响应。结果表明,不同主起落架传递的荷载在道面结构中也同样会发生叠加,引起结构中的应力增大,产生更大的表面的弯沉。

| Abstract: | Quote B747-400′s characteristics of large aircraft complex landing gear loading,base on the interaction of foundation-pavement structure-aircraft wheeling load,a methodology named three-dimensional finite element is put forward to establish multilayer composite system′s mechanical response model.Then use the model to analysis the stress-strain mechanical response of airport asphalt repaving runway,which indicate that it has superposition of different aircraft wheeling load,and that the inreading stress and deflection of airport pavement. |
