Abstract

The comprehensive understanding of the mechanistic behavior of airport pavements under aircraft landing loads is essential for ensuring safety and durability. Addressing the limited understanding on the interaction between aircraft landing gear and airport pavement during landing, this study proposed a measurement method for the vertical dynamic contact characteristics of tire-pavement interface and internal dynamic responses based on a laboratory dynamic test device. This involved the experimental design and testing method for the dynamic characteristics of landing gear landing loads, utilizing the Tekscan pressure measurement system to evaluate the vertical dynamic contact characteristics between the aircraft tires and pavement during landing. Through comparative analysis with the static results, the study revealed the importance of landing load measurements for mechanical response analysis and durability design of airport pavements. Additionally, the study investigated the dynamic response of airport pavements under different simulated aircraft landing speeds and weights, and further quantified the impact effects of aircraft landing loads on airport pavements. The results show that the vertical tire-pavement contact characteristics under landing impact are significantly different from those under static conditions, and need to be considered. The proposed quantitative equations with acceptable good fitting effect provided more accurate and efficient vertical load inputs for numerical simulation and durability design of airport pavements, which laid the foundation for understanding the failure mechanisms of airport pavement and enhancing the safety of aircraft and airport operation.

飞机着陆冲击载荷的表征：对垂直轮胎-路面接触特性和路面性能的影响

全面了解机场路面在飞机着陆载荷作用下的力学行为，对于确保路面的安全性和耐久性至关重要。针对飞机起落架在着陆过程中与机场路面相互作用认识有限的问题，提出了一种基于室内动力试验装置的轮胎-路面界面垂直动态接触特性及内部动力响应测量方法。这涉及到起落架着陆载荷动态特性的实验设计和测试方法，利用Tekscan压力测量系统来评估飞机轮胎与路面在着陆过程中的垂直动态接触特性。通过与静力结果的对比分析，揭示了着陆荷载测量对机场路面力学响应分析和耐久性设计的重要性。此外，研究了不同模拟飞机着陆速度和重量下机场路面的动态响应，进一步量化了飞机着陆载荷对机场路面的影响效果。结果表明：着陆冲击下轮胎与路面的垂直接触特性与静态条件下有显著差异，需要考虑；所提出的定量方程拟合效果良好，为机场路面的数值模拟和耐久性设计提供了更加准确、高效的竖向荷载输入，为了解机场路面破坏机理，提高飞机和机场运行的安全性奠定了基础。
