摘要: 湿滑条件下飞机着陆安全性一直是航空安全领域的研究重点。采用数值模拟方法研究了机轮在湿滑道面上的滑跑过程,基于空客A320型飞机的机轮子模型,建立了具有不同胎面花纹特征的机轮模型,并对胎面花纹进行了精细化处理;采用光学扫描及三维重构的方法,构建了具有SMA-13沥青道面纹理特征的道面模型;结合Heinrich橡胶材料与粗糙道面的接触模型,建立了机轮橡胶与机场道面的接触模型,并实现了橡胶胎面与道面间的接触;运用欧拉-拉格朗日(CEL)算法实现了水膜与道面、机轮间的流固耦合模拟。基于提出的机轮滑水有限元模型,用道面与机轮的接触力、临界滑水速度等特征指标分析了飞机滑跑速度、水膜厚度、机轮荷载、胎面花纹和机轮胎压等因素对机轮滑水性能的影响。

Abstract: Aircraft landing safety under wet conditions has been the focus of research in the field of aviation safety. Based on the main wheel of Airbus A320 aircraft, a aircraft tire model with different tread pattern characteristics and the refined tread pattern model were developed. Using optical scanning and 3D reconstruction, a runway surface model with gradation of SMA-13 asphalt mixture was constructed. Combined with Heinrich contact algorithm between rubber and rough runway surface was obtained, and the contact model between tread rubber and runway surface was developed. The Coupled-Eulerian-Lagrange (CEL) algorithm was used to solve the fluid-solid interaction between water film and runway surface and aircraft tire. Based on the proposed finite element model, the influence of aircraft landing speed, water film thickness, tire load, tread pattern and tire pressure on the hydroplaning was analyzed by the contact force between the runway surface and the tire and the hydroplaning speed.

Key words: aircraft tire hydroplaning, real texture, wet runway, hydrodynamic pressure, 3D reconstruction of runway surface
