基于ADAMS的机场道面平整度评价方法

An Evaluation Method for Roughness of Airport Pavement Based on ADAMS

现有机场道面平整度评价标准没有按照飞机在跑道和滑行道滑行速度的不同加以区分,针对这一问题,在确定飞机在滑行道和A、B两级机场跑道代表速度的基础上,以3m波长作为机场道面最不利波长、0.40g作为不舒适的评价标准,利用机械系统动力学分析软件ADAMS对飞机作用下的道面动态响应进行分析,得到不同道面平整度的最大凹陷允许标准。分析结果表明:滑行道道面平整度的最大凹陷允许标准为57mm,A级机场道面平整度的最大凹陷允许标准为12mm,B级机场场道面平整度的最大凹陷允许标准为19mm;道面最大凹陷允许标准与飞机滑跑速度密切相关,而不依赖于机场等级。

Aimed at the problem that airport pavement roughness evaluation indexes and standards fail to make strict distinction between the two different slipping speeds of aircraft respectively on runway and taxiway in existing standard,taking three-meter wavelength as the most disadvantageous wavelength to airport pavement,and taking 0.40g as a discomfort evaluation standard on the basis of airplane speed rep-resentative value on the taxiway and on runway of airport rand A and rand B,this paper analyzes the dy-namic response of pavement under the action of aircraft by using software ADAMS.The analyzed results show that allowable roughness of taxiway pavement is 57 mm and runway for airport class A is 12 mm,for class B is 1 9 mm.The analytic results indicate that the allowable roughness is rather closely related with the airplane slipping speed than the airport classification.
