摘要: 为探讨双挂汽车列车在我国典型道路的适应性,基于车辆动力学建立两类双挂汽车列车仿真模型,在Trucksim平台搭建高速匝道、高速公路、U形转弯、立交以及十字交叉口等典型道路场景,基于最大扫过路面宽度和后部放大系数等指标对双挂汽车列车的道路适应性进行仿真评估。结果表明,部分场景外(转弯半径过小或路面附着系数过低)所搭建的两类双挂汽车列车均能沿目标轨迹正常行驶,对所搭建场景适应性较高;对比发现,C-double型双挂汽车列车后部单元与牵引单元轨迹重合度更高,通过性更好,而B-double型双挂汽车列车由于单元之间均为牵引座连接,行驶中更加稳定。

Abstract: To investigate the adaptability of double-trailer trains on typical roads in China, two simulation models for double-trailer trains were developed based on vehicle dynamics. Typical road scenarios, such as freeway ramps, freeways, U-turns, interchanges, and intersections, were constructed on the Trucksim platform. The road adaptability of double-trailer trains was simulated and evaluated based on maximum swept road width and rearward amplification factor. Simulation results reveal that  both models travel normally along the target trajectory and exhibit high adaptability to the constructed scenarios, except for scenarios with excessively small turning radii or low road adhesion coefficients. A comparative analysis reveals that the rear unit of the C-double model achieves a higher degree of trajectory coincidence between the rear unit and tractor unit, thereby demonstrating better pass ability, whereas the B-double model, with wheel connections between all units, is more stable during driving.

Key words: vehicle engineering, double-trailer train, vehicle dynamics, typical road scenarios, road adaptability, rearward amplification
