摘　　要：车辆的稳态转向特性直接影响到其工作效率以及安全性。建立了轮式车辆稳态滑移转向的数学模型并提出了数值求解方法,最后基于某4×4全地形车,仿真分析了车速和转向中心线移动量对其转向性能的影响。仿真结果表明:转向半径越小,滑转、滑移越严重,车辆受到的转向阻力越大;地面附着系数越大,车辆受到的牵引力和制动力越大,转向消耗的功率更多。The stationary turning performance of vehicles directly affects the work efficiency and work security of vehicles. In this paper, the mathematical model for the stationary skid-steering process of wheeled vehicles is set up and the numerical method for analyzing the stationary turning performance is given. Based on a 4×4 all-terrain vehicle, the effect on vehicle turn- ing performance of turning center hne excursion is simulated and analyzed. The result shows that, with less turning radius, vehicle is affected by much severer slippage and turning resistance; with greater adherent coefficient, vehicle is affected by more traction and braking force and power consumption.
