摘　　要：本文以A320主起落架轮胎与装配式道面板为研究对象,首先,基于能量损耗理论及摩擦学基本原理,建立轮胎与道面之间的能量耗散方程,从而得出道面宏观构造特征参数与摩擦耗散之间的量化关系。其次,利用ABAQUS建立飞机轮胎-道面板相互作用动力仿真模型。最后,通过仿真实验得到最优的装配式刻槽道面的构造特征参数(刻槽深度、刻槽宽度、刻槽倒角),结果表明:当刻槽宽度为30 mm、刻槽深度为2 mm、刻槽倒角为45°时,装配式道面板可以显著增强道面抗滑性能,具有良好的摩擦耗散性能,与轮胎接触面更大,抓地性能更好,可以提高装配式道面板的耐久性。The research object is the main landing gear tires of A320 and the assembled slab,based on the theory of energy dissipation and the basic principles of tribology,the energy dissipation equation between tire and pavement is established,and the quantitative relationship between pavement macrostructural characterization parameters of pavement and frictional dissipation can be obtained.Then,dynamic simulation model of tire-slab interaction is established using ABAQUS.Finally,the optimal constructional characteristic parameters(groove depth,groove width and groove chamfer)of assembled grooved pavement can be obtained through simulation experiment.The results show that assembled slab with groove width of 30 mm,groove depth of 2 mm and groove chamfer of 45°can significantly enhance the skid resistance of the pavement and has excellent frictional dissipation property,also provide a larger contact area with the tires,leading to better traction performance,which can effectively enhance the durability of assembled slab.
