摘要：
Based on the semi-analytical finite element model NASP, the simulation of aircraft braking taxiing was derived and realized. Taking B738 aircraft as an example, the influence of runway pavement structure and aircraft's speed on the dynamic response of runway under the braking force of single wheel and multi-wheels was analyzed, and the mechanism of aircraft braking taxiing affecting runway fatigue life was revealed. The results show that the aircraft with high-speed emergency braking will cause a significant increase in the longitudinal stress of runway structure surface, and then sharply shorten the fatigue life of airport runway. The additional longitudinal tensile stress caused by braking force still has a high amplitude when the aircraft taxies at low speed. The influence of braking force must be considered in runway structure design. © 2022 Central South University of Technology. All rights reserved.
