摘　　要：对舰载机无杆式牵引车的行驶稳定性进行了理论研究,仿真和量化分析了重要参数质心位置对行驶稳定性的影响.考虑舰船多自由度耦合运动对牵引车产生的惯性力,建立了2自由度时变非线性舰载机无杆式牵引车系统动力学模型,理论研究了目标系统的稳定性和系统不稳定表现形式的判定方法,给出了系统稳态响应和频率响应的求解方法.建立了系统动力学仿真模型,通过仿真实验和敏感度计算,量化分析了质心位置的变化对牵引车行驶稳定性的影响程度,为舰载机无杆式牵引车行驶稳定性的研究提供了理论基础和优化方向.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.
