摘要： 建立了6×4牵引车与3轴半挂车组成的半挂汽车列车11自由度半车动力学模型，在道路不平度的激励下通过频域方法研究了牵引车的驱动桥平衡梁及全浮式驾驶室的不同处理方法对半挂汽车列车平顺性仿真结果的影响。之后，进一步研究了悬架刚度、悬架阻尼系数、轮胎刚度、牵引销前置距及挂车上货物质心位置变化对半挂汽车列车平顺性的影响，并按照其影响的大小进行了排序。这些工作为半挂汽车列车的设计及牵引车与半挂车的匹配提供了一定指导。

Abstract: The half vehicle dynamics model with 11 degrees of freedom of the combination which was composed of 6×4 tractor and semi-trailer with 3 axles was eatablished. The effects of the processing methods of the equilibrator suspension system and the fully suspended cab on the ride performance of the combination were investigated by frequency domain method under the excitation of road roughness. and then MATLAB was used to compile program. Further, the research on the effects of the parameters of suspension stiffness and damping, tire stiffness, fifth-wheel lead and the centroid position of goods on the ride performance of the combination were also carried out, and these effects were sorted by magnitude. The results of the two models were compared. These efforts will provide some theoretical guidance for the design of semi-trailer tractor combination and the match between tractor and semi-trailer.

Key words: vehicle engineering, tractor-semitrailer combination, ride performance, match, structure parameter
