摘要
为减少多轴车辆低速转向时的转向半径,以某6×6前四轮转向车辆为研究对象,提出全轮转向系统的改装方案。建立全轮转向三轴车辆的二自由度模型,基于质心零侧偏角比例控制策略,推导转向中心到前轴的距离、转向半径等公式。运用MATLAB软件,对全轮转向车辆的转向性能进行仿真分析。结果表明:采用全轮转向技术能减少车辆低速转向时的转向半径,提高车辆的机动灵活性。
In order to reduce the steering radius of the multi-axis vehicle at low speed steering, taking a 6x6 vehicle with front four-wheel steering as the research object, the all-wheel steering system conversion program is put forward. Building the 2-DOF model of three-axle vehicle with all-wheel steering, based on zero side-slip angle of mass center and proportional control strategy, the formula about the distance from the steering center to the front axle and the steering radius are obtained. Using MATLAB software, the steering performance of the vehicle with all-wheel steering is simulated. The resuhs show that the all-wheel steering technology can decrease the steering radius at low speed, increase the mobility and flexibility of the ve- hicle.
