摘　　要：为解决汽车列车最大摆动幅度测试难题,提出了一种新的测试方法,以某铰接列车为研究对象,用陀螺仪和差分基站测试了半挂牵引车、半挂车关于直线基准线的行驶轨迹,计算出摆动幅度,对比了50 km/h与30 km/h车速时的最大摆动幅度。结果表明,此方法能有效表达汽车列车的行驶轨迹和摆动幅度,最大摆动幅度的相对标准偏差为19.7%,50 km/h车速时的最大摆动幅度比30 km/h车速时的增加了66%,此方法可为车道的直线宽度确定和汽车直线行驶稳定性的测试提供参考。To address the challenge of measuring the maximum swing amplitude of combination vehicles,a new testing method was proposed.An articulated vehicle was tested using gyroscopes and Real-Time Kinematic(RTK)base stations to track the driving trajectory of both the tractor and the semi-trailer relative to a straight reference line.The swing amplitude were calculated,and a comparison was made between the maximum swing amplitudes at speeds of 50 km/h and 30 km/h.The results indicate that this method effectively obtained the driving trajectory and swing amplitude.The relative standard deviation for the maximum swing amplitude was 19.7%,and the maximum swing amplitude at 50 km/h increased by 66%compared to that at 30 km/h.This proposed method provides a reference for determining lane width and testing vehicle stability during straight-line driving.
