The coupling action between the aircraft and the pavement should not be ignored for studying the landing and taxiing of an aircraft and the vibration of the pavement.ĬAAC (Civil Aviation Administration of China) (2019) Specifications for pavement evaluation and management of civil airports, MH/T 5024-2019ĭong Q, Wang JH, Zhang XM, Wang H, Zhao JN (2021) Dynamic response analysis of airport pavements during aircraft taxiing for evaluating pavement bearing capacity. The results show that properly increasing the N-SS damping can reduce the numbers and amplitudes of the aircraft’s bounce after landing and the aircraft–pavement coupling action has a more significant influence on the pavement dynamics such as DLC and PVD than the uncoupled system for an excellent pavement in hard soil foundation. Numerical analysis has been carried out in detail to detect the law of the coupled system’s response by changing the international roughness index (IRI) of the pavement and the N-SS damping. The vibration characteristics of the discrete coupled system under the aircraft lift and the pavement roughness are studied by the suspension system vertical displacement (SSVD), the non-suspension system vertical displacement (N-SSVD), the dynamic load coefficient (DLC), and the pavement vertical displacement (PVD). The multi-degree-of-freedom governing differential equations of the coupled system is obtained by the Galerkin treatment of the beam equation. MethodsĪ rigid pavement is abstracted as a finite length Euler–Bernoulli beam on a finite length Pasternak foundation, and a two-degree-of-freedom (2-DOF) aircraft model which consists of a suspension system (SS) and a non-suspension system (N-SS) is coupled to the abstracted beam model to describe the point-to-point contact of the aircraft tires with the pavement when the aircraft lands and taxies on the pavement. The dynamic response of the aircraft–pavement coupled system in different pavement IRIs, soil stiffness coefficients, and damping of aircraft’s non-suspension system are studied to provide a potential theoretical guidance for the mechanical properties evaluation of an airport runway. This paper focuses on the modeling and dynamic analysis of an aircraft–pavement coupled system.
