摘要：

机场沥青道面设计中，土基顶面机轮荷载有效作用宽度对确定飞机作用次数具有重要影响。采用ANSYS软件分析方法，以单轴单轮荷载为基础研究土基强度尧等效面层厚度与机轮荷载有效作用宽度之间的变化关系。对于复杂起落架结构，在考虑荷载叠加效应的条件下，探讨如何协调解决多个机轮间相互作用对荷载有效作用宽度的影响问题。结合分析成果，提出复杂起落架构型下飞机荷载有效作用宽度的计算方法。

Abstract:

The effective width of aircraft tire loads at the top of subgrade has a significant effect on calculating the load repetitions in designing an airport asphalt pavement. The relationship between the effective width of aircraft tire loads and subgrade strength, equivalent surface thickness is researched basing on a single wheel by ANSYS. For a complex main gear, multiple tires will lead to load interaction. How to approach the effect of load interaction on effective width of tire loads of complex main gear is also discussed. According to these analyses, calculation method of tire loads‘effective width of complex main gear is achieved.

Key words: asphalt pavement, load repetitions, effective width, gear
