| 摘 要： | 为了分析机场跑道加铺道面结构在大型飞机多轮荷载作用下的空间响应规律,明确分析模型的合理计算范围和边界条件,应用大型通用有限元软件ABAQUS,建立了沥青混凝土加铺结构三维有限元模型.通过分析B747-400ER和A380-800等大型飞机多种轮载组合方式作用下的道面结构响应规律,以应力收敛为依据,确定了两种大型飞机的最不利荷载组合和分析模型规模:B747-400ER可采用后8轮组作为飞机最不利荷载组合,A380-800可采用3轴双轮6轮组作为飞机最不利荷载组合,道面结构模型平面尺寸应不小于15m×15m.

| Abstract: | In order to analyze structural response of airport asphalt repaving runway,and determine reasonable model dimension and boundary condition,based on ABAQUS software,a composite 3D FE model of asphalt repaving pavement was established,and structural response patterns under various loading configurations of B747-400ER and A380-800 were presented.By means of stress convergence analysis,the critical loading position and the reasonable model dimension are obtained.It indicates that 8 wheel groups for B747-400ER a... |
