摘要/Abstract

摘要： 利用美国联邦航空管理局（FAA）开发的跑道平整度分析软件ProFAA，对常见民用机型B727、B737 和B747 在随机激励、余弦激励和实测道面激励下进行滑跑仿真，研究飞机动力响应与滑跑速度、激励波长和振幅、道面平整度指标等因素的关系。仿真结果表明院飞机动力响应与滑跑速度和激励振幅成正比；飞机对中长波的不平整激励更敏感，敏感波长取值与机型和滑跑速度相关；飞机滑跑动力响应随道面平整度指标的增大而增大，但各项平整度指标与飞机动力响应之间的相关性不同，其中波音平整度指数（BBI）与飞机动力响应的相关性最高。

Abstract: The runway roughness analysis software ProFAA developed by FAA is used to run simulation on common commercial aircraft types such as B727, B737 and B747 under random excitation, cosine excitation, and measured runway excitation, studying the relation between aircraft dynamic response and speed, wavelength, amplitude as well as roughness indices. Simulation results show that: the aircraft dynamic response is proportional to the taxiing speed and excitation amplitude; aircrafts are more sensitive to the unevenness excitation of medium and long waves, and the value of sensitive wavelength is related to the aircraft type and taxiing speed; the increase of roughness indices aggravates the dynamic response of aircraft, but the correlations among them are different, BBI (Boeing bump index) has the highest correlation with the dynamic response of aircraft.

Key words: unevenness excitation, aircraft taxiing dynamic response, influencing factor, proFAA
