缓速器对半挂汽车列车制动稳定性的影响
Influence of Retarder on Brake Stability of Tractor-semitrailer
摘要
Abstract
or:A 7-DOF model of tractor-semitrailer was built with due considerations of the influ-ence factors,such as longitudinal load transfer and nonlinear tire model.The model was set up by the Simulink module of MATLAB.The results of the simulation show that:if road adhesion coefficient is high,the tractor-semitrailer will has a good performance of brake stability when retarder is at the 1st to 3rd gear,and when retarder is at the top gear,the tractor-semitrailer has a tendency of unstability, but it does not lose control completely.But if road adhesion is low,the tractor rear axle will lock up firstly even if retarder is at the 1st gear,which can make tractor sideslipe,so that it will cause the tractor-semitrailer jackknife,lose control completely.关键词
