Abstract: The Engineered Materials Arresting System (EMAS) is used to prevent aircraft from overrunning the end of the runway and it must ensure the safety of the passengers during the arresting process. A dynamic model of the EMAS for passenger safety analysis is constructed as a set of nonlinear dynamic equations. Then, by phase-space transformation, the model is transformed into first-order nonlinear differential equations, which are numerically solved by Runge-Kutta method, and a simulation program is also completed. An example is presented to illustrate that the present method is reasonable and creditable, with which the safety of the passengers during the arresting process can be estimated.
