An optimization technique of braking force distribution coefficient for truck

Braking force distribution coefficient of the axles influences the braking efficiency and the directional stability when the truck is braking. So, reasonable distribution coefficient is very important for traffic safety. Truck generally travels on the road that has a certain range of adhesion conditions. Through calculating the max value of truck brake efficiency in the certain range of adhesion conditions, the paper defines the optimal distribution coefficient, and applies this kind of technique to optimize the braking force distribution coefficient of one kind of FAW truck. It also compares the optimized front and rear curve of utilization adhesion coefficient and severity of braking with the curve before optimization, and analyzes the curves. Finally, the paper conducts road test of a truck. The results show that the technique can improve brake efficiency of truck and have good practical value.
