【摘要】 建立了双半挂汽车列车的运动学模型,给出了其转弯运动轨迹的一种求解方法,并用MATLAB软件仿真得到各个车辆单元,包括牵引车前轴和后轴、第一节半挂车后轴和第二节半挂车后轴转弯运动的轨迹。最后通过不同结构参数包括半挂车轴距和铰接点位置的设定,对比分析了各轴中点运动轨迹的变化;研究结果表明,对半挂车后轴进行主动转向控制,能有效改善双半挂汽车列车的转向灵活性和运行稳定性。更多还原

【Abstract】 The kinematics model and solving algorithm of turning trajectory of B-double vehicles are proposed.The trajectories of the front and rear axles of the tractor,the rear axle of the first semitrailer and the rear axle of the second semitrailer are simulated using MATLAB.By changing the structurla parameters including the wheel base of the semitrailers and the position of the articulated point,comparative analysis of the trajectory of each axle center is carried out.Results show that by control of the corner of rear axle of the semitrailer,the handling stability and the flexible steering of B-double vehicles can be improved.更多还原
