This paper theoretically studies the driving stability of a carrier based aircraft towbarless tractor, and simulates and quantifies the influence of the centroid position, an important parameter, on driving stability. Firstly, considering the inertia force on the tractor produced in carrier multi degree of freedom coupled motions, a two degree of freedom time varying nonlinear dynamics model of the carrier based aircraft towbarless tractor is established. The stability of the target system and the method of judging the unstable form of the system are studied theoretically. Then, the calculation methods of steady state response and frequency response of the system are given. A dynamic simulation model of the target system is established. Finally, the influence of the centroid position on the driving stability of the tractor is quantitatively analyzed through the simulation experiment and sensitivity calculation. It provides the theoretical basis and optimization direction for the driving stability analysis of carrier based aircraft towbarless tractors. |
