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。
Aircraft over-boundary engineering materials block system is used to prevent aircraft from running out of the special device. Firstly, the structure and working principle of engineering material block system are expounded. Then, the system dynamics model is established through reasonable assumptions and simplifications, and the problem is reduced to a set of nonlinear dynamic equations. On this basis, the model is transformed into first-order differential equations by phase-space transformation, then the equations are solved by Runge-Kutta method and the numerical simulation of the model is realized. The simulation results show that the established dynamic model is reasonable and the numerical simulation is feasible.
