【Abstract】 The road train is a complex system with interaction and coupling between the tractor and trailer.The study on lateral stability is multidisciplinary such as multi-rigid dynamics,rigid-flexible coupling mechanics,aerodynamics,nonlinear vehicle kinematics and electronic controllability.This paper introduced current status of the development,study method and test means about the tractor-trailer lateral stability at home and abroad.The effects of use and structure parameters on the tractor-trailer lateral stability were discussed.At the same time,the lateral acceleration response to step input of steering angle was also analyzed in this paper.Lastly,digital simulation algorithm of the tractor-trailer dynamics was analyzed,and typical simulation models were presented.更多还原
