Resumo
This study verified the accuracy and efficiency of different simulation models for airport pavements, focusing on vertical deformation at the top of the subgrade. Using ABAQUS 2020 software, complete 3D models, symmetrical 3D models, and a 2D model (reproduced in AEMC software) were compared. The research problem was the importance of understanding aircraft landing gear configurations and how they influence load distribution on the pavement. Landing gear configurations, such as single wheel, dual wheel, and dual tandem, among others, have a direct impact on pavement response, requiring precise modeling for accurate life expectancy estimates. The models were subjected to loads from a Boeing B767 aircraft to determine the impact on subgrade top deformation and simulation time. The results showed that 3D models offer greater accuracy compared to the 2D model, which exhibited higher deformations. However, symmetrical 3D models stood out by significantly reducing simulation time without compromising accuracy. It was concluded that the adoption of 3D models, especially symmetrical ones, is recommended for airport pavement design.
