Study on the Dynamics on the Brake of Vehicle after the Effects of Deicing Salt

摘要

Through analyzing the process of brake, a dynamic model of automobile and a model of the relationship between braking distance and adhesion coefficient were formed;also a simulation calculating model of braking distance was established with the use of Matlab. Finally, a research was done toward the braking distance of a type of a car running on a road after using snow-melting agent. On one hand, with the application of the simulation model which has been established, calculations have been done to the braking distance of Bora vehicles running on roads after using deicing saon the other hand, by experiments, Bora vehicles' braking distance and maximum braking deceleration under the same road condition were measured, meanwhile, the established simulation model was verified.
