Abstract:

:?根据GB1589—2004和GB/T12540—2009对外摆值的定义、限值和实验测试方法,参考半挂汽车列车在转弯通道圆内转弯过程的作图法,对半挂汽车列车外摆值的数值计算方法进行了研究。首先,研究了基于惯性坐标系和连体坐标系转弯过程的定量分析方法,推导出了半挂汽车列车外摆值的计算方法,并针对具体的车辆进行了数值计算与分析。然后,计算分析了牵引车与半挂车几何参数变化对外摆值的影响规律。最后,为验证所提半挂汽车列车外摆值数值计算方法的正确性,利用TruckSim工程软件进行了半挂汽车列车外摆值仿真,同时还进行了实车试验。研究结果表明:该算法计算结果准确、公式简洁、便于理解和工程实用,可为半挂汽车列车的通过性研究提供指导。
