Road Passing Analysis and Test Study of Semi-trailer Traction Train

Taking the low-plate semi-trailer as the research object, the calculation model of road passability is established, and the two parameters of the minimum turning diameter and turning channel width are analyzed based on the analytical method. According to the requirements of GB1589-2016 vehicle channel circle and the test method for the limit and measurement method of the vehicle turning channel circle diameter, and the circle and external pendulum value of the turning channel of a semi-trailer tractor are studied. Firstly, the low flat semi-trailer is established as the research object; secondly, according to the circle and the test method of the national standard, the comparison test is carried out to verify the correctness of the analytical analysis, the calculation result and the test error are very small, the model is credible, and the performance of the vehicle road meets the use requirements.
