飞机道面 EMAS 阻滞性能建模分析

摘要

结合实际情况，对机轮作用下 EMAS 的破坏作用做了静力学分析。在此基础上，对系统作了适当的假设和简化，建立了含有耗散函数的 Lagrange 动力学方程。此外，运用 MATLAB 软件对该动力学模型进行了仿真，得到了飞机在 X、Y 方向上位移和速度随时间变化的曲线，较好地描述了真机在 EMAS 阻滞状态下的实际情况，验证了该系统模型的有效性，为飞机道面 EMAS 的进一步研究提供了有效的理论支持。%Combining with actual situation, the statics analysis under the action of the wheel of EMAS is made. On this basis, the system makes reasonable assumption and simplification, and establishes dynamics equations of Lagrange con-tains dissipative function. In addition, using the MATLAB to simulate the dynamic model, the system obtains the curve changes with the time of the X,Y direction of the plane, and describes the actual situation of the plane in the arresting condition of EMAS, and verifies the effectiveness of the model, which provides effective theoretical support for further research of EMAS of aircraft-pavement.
