甲板上舰载机牵引系统的行驶特性分析

Moving characteristics analysis of carrier-based aircraft traction system on deck

对甲板上飞机有杆牵引系统的行驶特性进行仿真分析。考虑舰船横摇、纵摇和垂荡3个自由度的耦合运动对牵引系统产生的惯性力,建立三自由度时变、非线性牵引车-飞机系统动力学模型。借助Matlab/Simulink以及多体系统动力学软件,研究甲板上牵引系统的行驶特性机理,给出牵引系统在不同海况、负载状况、行驶速度等条件下的表现特征。理论分析和仿真结果表明:海况以及负载是影响舰载机牵引系统行驶特性的主要因素。当系统以不同速度行驶时能够很快地达到稳定状态,即使在侧风扰动后,仍表现出良好的操纵稳定性。

To study on the moving characteristics of a tractor-aircraft system, considering the inertial force on the aircraft traction system produced by coupled roll-pitch-heave motion of ship, a time varying, nonlinear 3DOF tractor-aircraft system dynamic model was established. By means of the control software MATLAB/Simulink and the multi-body dynamics software, the inspection of mechanism of the tractor-aircraft moving behavior on deck was researched and the main experimental characteristics of expression in various marine environment, different load status and running speeds were recounted. Investigation of the carrier-based aircraft towed moving performance shows the influence factors of the tractor-aircraft system. Theoretical verification and experimental results indicate that the first two factors significantly influence the moving performance of the tractor-aircraft system. Responses of system to running speeds regain steady-state quickly. Traction system performs well in handling stability even with crosswind disturbance.
