Description
Summary:This paper uses TruckSim dynamics simulation software to build a non-linear model of a center-axle trailer combination, conducts a braking in a turn simulation to study its braking in a turn stability, and a straight-line braking test was carried out on the train through the built-up centre-axle trailer combination braking performance test system, and the reliability of the simulation model was ensured by comparing the test and simulation results. In order to improve the braking performance of the train, a comprehensive evaluation index for evaluating the braking performance of the train is proposed by taking the structural parameters of the train as the optimization variable. The uniform test method is used to optimize the design of the variables, and the braking in a turn is performed on the high adhesion road. Simulation and analysis results show that the optimization reduces the probability of brake folding and improves braking stability.
