Stability Simulation Research of Tractor-Semitrailer Braking in a Turn

摘要

A dynamic model of tractor-semitrailer braking in a turn was established in this paper. By comparing the data of tractor-semitrailer test, a high credibility of the simulation model was certified. In this paper, yaw rate gain and folding angle gain were introduced to evaluate the stability of tractor-semitrailer braking in a turn, and the role played by ABS was analyzed. The results show that yaw rate gain and folding angle gain are very comprehensive evaluating indicator, and ABS plays an important role in improving the stability during braking in a turn of tractor-semitrailer.
