Abstract
AbstractGiven the coupled tractor-trailer interacting with each other, road train is a complex system. The study on lateral stability of tractor trailer system is related to several fields such as multi-rigid dynamics, rigid-flexible coupling mechanics, aerodynamics. The research about the tractor-trailer lateral stability involves multi-discipline, multi-dimension, complex system, nonlinear vehicle kinematics and electronic controllability. Overview is made of the current development, method and test means about the tractor-trailer lateral stability study at home and abroad. The effects of parameters use and structure on the tractor-trailer lateral stability study are discussed. At the same time, the lateral acceleration response to step input of steering angle is also analyzed. Digital simulation algorithm of the tractor-trailer dynamics is presented, as well as typical simulation models.
