| 摘 要： | 建立了多轴车辆定比例转向系统理想模型和多轴车辆侧向动力学模型,通过对两模型定比例转向时的低速转向半径进行比较,验证了多轴车辆侧向动力学模型的合理性.基于该模型,分别分析了定比例转向系统和变比例转向系统的低速转向半径和高速操纵稳定性.结果表明:定比例转向的多轴转向系统低速机动性不够好,且高速稳定性很差;变比例转向的多轴转向系统在提高车辆机动性的同时,还能改善车辆的高速稳定性.

| Abstract: | Multi-axis steering vehicle fixed ratio steering system model and lateral dynamics model are established. By comparison to the low-speed turning radius of two models with fixed ratio steering, the rationality of lateral dynamics model is verified. Based on this model, the low-speed turning radius and high-speed handling stability are respectively analyzed with the ratio of front wheel to rear wheel fixed and the ratio changing with the speed. The results showed that the fixed ratio steering system has good low-speed maneuverability, but its high-speed stability is poor; the other steering system not only enhances vehicle mobility, but also improves the vehicle’s high-speed stability. |
