摘　　要：飞机越界工程材料阻滞系统是用来防止飞机冲出跑道的专用装置。该文首先阐述了工程材料阻滞系统的结构和工作原理,然后通过合理的假设和简化建立了系统的动力学模型,将问题归结为一组非线性动力学方程。在此基础上,通过相空间变换将模型转化为一阶微分方程组,然后采用Runge-Kutta方法对方程组进行求解,并编程实现了模型的数值仿真。仿真算例表明:建立的动力学模型是合理的,数值仿真是可行的。The engineered materials arresting system（EMAS） is used to prevent civilian aircraft from overrunning the end of the runway.This paper describes the structure and EMAS working principle.Then,a dynamic model of the EMAS is constructed as a system of nonlinear dynamic equations.The model is transformed to first-order differential equations by a phase-space transformation,which are numerically solved by the Runge-Kutta method.An example is presented to illustrate that the dynamic model reasonably predicts the motion of the EMAS during contact of with a plane.
