Research on Lateral Stability of Tractor-Semitrailer Steering and Braking Based on Nonlinear Factors

Article Preview

Abstract:

A 18-DOF tractor-semitrailer nonlinear dynamics model was developed to describe the travelling characteristics of tractor-semitrailer braking in the cornering, considering the related nonlinear factors on the vehicle such as load transfer, saddle and tire. On this basis, it was calibrated that vehicle simulation model is reliable through real vehicle test. It was further analyzed the effects on lateral stability such as saddle position, load, braking force distribution and inside/outside wheel braking force difference through simulation when tractor-semitrailer braking in a turn.
