Abstract

Body sway is a common dynamic instability phenomenon in automotive engineering. It is more likely to occur in car-trailer combinations than in the passenger cars because of the coupling between the towing car and the trailer. The corresponding theoretical studies have been carried out to find the mechanism of body sway. Most theoretical studies mainly focus on the suspension subsystem and wheel subsystem, but the influence of steering system characteristics is often neglected. In this paper, a theoretical model with 6 DOFs of CTCs is established by Lagrange equation. The stiffness, damping and dry friction of the steering system are considered in this model. The dynamic stability of CTCs is indicated by the system dynamic critical speed. The dynamic analysis becomes more complex because of the introduction of the nonlinearities of tire and dry friction. The steering characteristics have different influences on the dynamic critical speed. Especially, the excessive dry friction does harm to the dynamic stability of CTCs. The effect chain between the steering system characteristics and body sway of CTCs could be revealed through theoretical analyses and the simulation study.
