摘要
在重型多轴车辆智能化、无人化的发展趋势下,需要开展车辆横向动力学研究。针对某六轴车辆,通过建立多轴车辆线性二自由度转向模型,开展转向特性稳态分析和瞬态分析。仿真结果定性地表明采用多轴转向技术能够有效提升车辆转向机动性,为后续转向控制器设计提供了理论支撑。
With the development of intelligent and unmanned heavy-duty multi-axle vehicles,it is necessary to conduct research on vehicle lateral dynamics.By establishing a linear two-degree-of-freedom model of a multi-axle vehicle,the steady-state and transient analyses of the steering characteristics of a six-axle vehicle are performed.Simulation results qualitatively show that the use of multi-axle steering technology can effectively improve the steering maneuverability of the vehicle and provide theoretical support for controller design in the future.
