摘　　要：应用相似模型理论对半挂汽车列车模型进行了相似关系分析.在建立汽车列车横向动力学模型的基础上,在汽车列车横摆模拟实验台上,对在不同车速、不同结构参数条件下的汽车列车横向摆振特性进行试验,并对试验结果和数字仿真结果进行对比分析.研究结果表明:理论计算结果与模型试验行为具有很好的一致性,这种方法为提高试验系统性能和向原型车辆反推提供可行性.According to the scale model theory, the similarity of semi-trailer model was analyzed with scale 1∶17.4. Based on the analysis of the lateral dynamics of tractor-trailer combination, tests on snaking characteristic of the scale model of tractor-trailer are carried out at different velocities and parameters. By comparing the results of the scale model test and the digital simulation, a conclusion was drawn that the mathematical simulation and model test simulation agree well so as to provide the feasibility of improving the capability of test and reverse-deducing to real tractor-trailer combination.
