为了使未来的大型运输机尽量与我国现有机场道面能达到的承载力相适应,在调查大量机场道面结构类型、结构层厚度、道面承载强度、所受过的最大胎压的基础上,根据机场道面超载使用的相关规定,从尽量减少机场改造的角度,对未来大型运输机的ACN(Aircraft Classification Number)及胎压提出了建议值.建立了足尺9块道面板三维有限元分析模型,对大型运输机采用建议值以单轮I、L-76飞机以及C-5运输机等不同起落架构型作用下的道面结构响应进行了求解.为了达到尽量少改造现有机场的目的,未来大型运输机的ACN在16.1~24.2之间取值以及胎压不高于0.80 MPa比较合理,现有机场道面承载力可保障其在50%以上的机场上正常起降.
In order to adapt the large transport aircraft in the future to the bearing capacity of the existing aerodrome in our country, based on the investigation of a large number of aerodrome structure types, the thickness of the structural layer, the bearing strength of the pavement and the maximum tire pressure experienced, According to the relevant provisions of airport surface overloading, from the point of view of minimizing airport reconstruction, the proposed values of ACN (Aircraft Classification Number) and tire pressure of large transport aircraft are proposed.A three-dimensional finite element analysis model , The recommended value of large transport aircraft was solved with the response of the pavement structure under the different landing gear configurations of single-wheeled I, L-76 and C-5 transport aircraft.In order to achieve the goal of minimizing the reconstruction of existing airports, Transport aircraft ACN values between 16.1 to 24.2 and the tire pressure is not higher than 0.80 MPa is reasonable, the existing airport bearing capacity of the surface to ensure that more than 50% of its normal take-off and landing at the airport.
