摘　　要：为分析双挂汽车列车的轴荷分布状态与几何通过性能,本文基于Truck Sim仿真平台搭建了双挂汽车列车模型,在满载状态下研究了车辆各轴组的轴荷分布状态、最小转弯半径及转弯内轮差,并与半挂汽车列车进行了对比分析。结果表明:(1)双挂汽车列车较于半挂汽车列车无轴组载荷差异;(2)双挂汽车列车的最小转弯半径较半挂汽车列车增加0.59 m,同比增大4.07%;在十字交叉口弯道半径为20m时,双挂汽车列车右转内轮差较半挂汽车列车减小0.79 m,同比减小27.92%,扫掠面积减小7.15 m^(2),同比减小13.77%。表明双挂汽车列车通过弯道的性能更为优异。In order to research the axle load distribution and geometric passing performance of the double-trailer truck train,a model of the truck was constructed based on the TruckSim simulation platform.The axle load distribution of each axle group of the vehicle,the minimum turning radius and the turning inner wheel difference were investigated under the full load condition.A comparative analysis was then carried out with that of the semi-trailer automobile train.The results show that:(1)there is no obvious difference between the two types of vehicles in terms of axle load;(2)the minimum turning radius of the double-trailer truck train increases 0.59 m and 4.07%compared with the semi-trailer truck train.When the radius of the geometric at the intersection is 20 m,the right-turn inner wheel difference of the double-trailer truck train is reduced by 0.79 m and 27.92%compared with that of the semi-trailer truck train.Furthermore,swept area is reduced by 7.15 m^(2) and 13.77%.This finding suggests that the double-trailer truck train possesses a higher level of maneuver ability when negotiating curves in comparison to the semi-trailer truck train.
