| 摘 要： | 为了研究舰船上直升机牵引系统的动力学性能,分析影响其稳定性的主要因素,建立了运动甲板上牵引系统力学模型,分析了船体横摇、纵摇和垂荡3个自由度的耦合运动对直升机牵引系统产生的惯性力、轮胎垂直载荷对轮胎侧偏刚度的影响.在此模型基础上,推导了具有周期系数的四自由度扰动方程,运用Floquet理论分析直升机牵引系统运动稳定性.结果表明:2级以上海况下,牵引系统的临界速度与陆地上相比大幅度降低,最小降幅为70%;随着直升机与牵引车质量比的减少和牵引车后轮侧偏刚度的增大,牵引系统的稳定性提高.

| Abstract: | In order to study the dynamic performance of a helicopter traction system on deck,and analyze the factors influencing its motion stability,a dynamic model of the traction system was developed.In the model,the inertial force of the helicopter traction system produced by coupled roll-pitch-heave motion of the ship hull and the influence of variable vertical load on the tire cornering stiffness were considered.Based on this model,a 4 degree-of-freedom(DOF) perturbation equation with periodic coefficient was ob... |
