摘　　要：提出一个数学模型来描述飞机刹车过程.通过分析制动过程中飞机与机轮的受力情况,建立了一系列动力学方程求解整个制动过程中的关键变量.使用龙格库塔法求得动力学方程的解析解,通过RTX半实物实时仿真平台进行仿真,保证实时性能.仿真系统可根据实际情况改变实验参数,从而对不同路况下的飞机刹车进行仿真.A mathematical model was proposed to describe the aircraft brake process.Firstly,analyzing the force of the aircraft and its wheels,a series of dynamic equations were established to solve the key variables in the entire braking process.And then,a Runge-Kutta method was used to obtain the solutions of differential dynamics equations.Finally,a hardware-in-the-loop simulation platform RTX was established to simulate and guarantee the real-time performance.Results show that,the simulation system can adapt for the experimental parameter changes to simulate the braking process under different actual conditions.
