摘要:基于LuGre摩擦理论建立动态轮胎模型,仿真分析轮胎侧偏角和滑移率参数对轮胎纵向力和侧向力的影响。考虑车辆垂直载荷及转向系统的影响,搭建车辆联合动力学模型,以方向盘转角为输入,横摆角速度和质心侧偏角为评价指标进行联合仿真分析。结果表明:车辆联合动力学模型能够较好的体现方向盘转向输入时不同路面环境及车速下车辆的动态响应情况,对复杂路面环境的车辆操纵稳定性研究具有一定的参考价值。 |

Abstract: Establish a dynamic tire model based on LuGre friction theory, then simulate and analyze the effects of tire sideslip angle and slip rate parameters on tire longitudinal and lateral forces. Considering the influence of vehicle vertical load and steering system, building a vehicle joint dynamics model. Using steering wheel angle as input, yaw rate and center of mass sideslip angle as evaluation indicators, to conduct joint simulation analysis. The results indicate that: The vehicle joint dynamics model can better reflect the dynamic response of the vehicle under different road environments and vehicle speeds when the steering wheel is turned. It has certain reference value for the research of vehicle handling and stability in complex road environment. |
