摘要:
采用双转向系统的多轴车辆存在转向耦合干涉问题，且该问题与后轴主动转向控制策略密切相关。为了探索后轴主动转向控制对多轴车辆轮胎侧偏角及分布和车辆稳定性的影响，基于Dugoff轮胎模型，构建了以滑移率、质心侧偏角和转弯半径等为变量的双转向系统多轴车辆3自由度非线性模型。以5轴转向车辆为研究对象，仿真探讨了双转向系统多轴车辆的转向耦合干涉、驱动模式、车轮转角和后轴转向控制策略对轮胎滑移率、侧偏角及分布的影响。仿真结果表明：轮胎侧偏角从前轴到后轴逐渐减小，相对于全主动转向车辆，双转向系统车辆的轮胎侧偏角更大；车轮转角对轮胎侧偏角和滑移率具有明显影响；随着车速增加，后轴主动转向中心后移动速度越快，轮胎侧偏角越小，但轮胎磨损增大；全轮驱动比部分驱动的滑移率明显小，而侧偏角偏大，车辆安全稳定裕度更大。
Abstract:
A multi-axle vehicle with dual-steering systems(DSS) has steering coupling interference problem,which is closely related to the active steering control strategy of the rear axle.In order to explore the influence of active steering control strategy of the rear axle on tire side slip angle and its distribution and vehicle stability of a multi-axle vehicle,based on the Dugoff tire model,a 3-DOF nonlinear model of a multi-axle vehicle with DSS is established,which takes slip ratio,side slip angle and turning radius of mass center as variables.Taking a 5-axle steering vehicle as an example,the effects of steering coupling interference,driving mode,wheel steering angle and the rear axle steering control strategy on tire slip rate,side slip angle and its distribution of a multi-axle vehicle with DSS were simulated.The simulation results show that the tire side slip angle gradually decreases from the front axle to the rear;compared with the vehicle with full active steering,the tire side slip angle of the vehicle with DSS is larger;the wheel steering angle has a significant effect on the tire side slip angle and slip ratio;with the increase of the vehicle speed,the rear axle active steering center moves faster,the tire side slip angle become smaller but the tire wear increases;the slip ratio of the all-wheel driven vehicle is obviously smaller than that of a partial driven vehicle,while the side slip angle is larger and the vehicle safety and stability margin is greater.
