摘要
针对3轴车辆,通过建立非线性二自由度转向模型,开展转向特性分析,得到在轮胎大侧偏角情况下车辆的转向特性,仿真结果表明,转向行驶过程中,轮胎的侧偏角进入非线性范围,侧偏力对车辆转向特性产生明显影响,为多轴车辆转向特性分析提供理论支撑.
For a 3-axle vehicle, analyzing the steering characteristics by establishing a nonlinear two-degree-of freedom steering model, and the steering characteristics of the vehicle under the condition of large sideslip angle of tires are obtained. The simulation results show that the sideslip angle of tires enters the nonlinear range during steering and driving, and the sideslip force has a significant impact on the steering characteristics of the vehicle, which provides theoretical support for the analysis of the steering characteristics of multi-axle vehicles.
