Abstract

Abstract: To study the safety of semitrailers corner overtaking behavior, the dynamic model of vehicle, the road model and the drivers' aiming trajectory model were developed by multi-body dynamics simulation software TruckSim. The semitrailers were simulated in separate working conditions by changing the super-elevations, circular curve radius, vehicle turning radius and speed. Lateral load transfer rate was invoked as the evaluation index for evaluating the vehicle's safety. The model of six axle semitrailer side tumbling stability prediction was established through the Spss regression; the risk of overtaking on five separate bends of a western highway was evaluated by the model. Results showed that vehicle experienced an anti super-elevation during the overtaking process in curves. The risk of driving in the anti super-elevation section is higher with super-elevation increasing. The risk is high when the semitrailers change track at the design speed of 120km/h in curves with super-elevation of no less than 8%.
