摘要
为提高目前多轴转向车辆模型的精确度,以三轴车辆为研究对象,利用虚拟样机技术,在ADAMS/CAR中建立了三轴全轮转向车辆的动力学模型,依据三轴全轮转向车辆的零质心侧偏角转角控制策略,对全轮转向进行了相应设置。为验证车辆的操纵稳定性能,对其进行了仿真分析,主要考查其在低速大转角和高速小转角行驶情况下的响应特性,并与传统的前轮转向车辆进行了对比,结果表明全轮转向车辆在低速转弯时机动性高,中高速转向时稳定性好。
In order to improve the precision of multi-axle vehicles model,three-axis vehicles was taken as the research object,and the virtual prototype technology of three-axle steering vehicle was established using ADAMS/CAR.Based on zero side-slip angle of mass center and proportional control strategy,the three axles steering were set.The handling stability of the three-axle steering vehicle were simulated,compared with traditional front wheel steering vehicle,and the results showed that three-axle steering steering vehicle has better performance.
