Abstract
To analyze the influence of structure parameters on the road adaptability of double semi-trailer road trains, the authors built two double semi-trailer road train (B-train) models using TrackSim. The turning circle test and the road adaptability test were simulated on dry pavement to analyze the relationship between the structure parameters and the turning passing ability. The results show that the structure parameters have significant influence on the road adaptability of double semi-trailer road trains. A B-Train cannot meet the GB 1589-2004 national standard of limits of dimensions, axle load, and masses for road vehicles. However, a B-Train with a dolly and with the same length can meet the requirements, and the passing ability is better. Both double semi-trailer road train models will take up a lane beside itself when miming up to and including third-grade highway/ramps.
