Research on Angular Acceleration Gain Coefficient Performances of Driving Wheels

The performance of angular acceleration gain coefficient of driving wheels is investigated in this paper. To identify the interrelations between vehicle and road, the changes of parameters in wheel slip process were analyzed and the concept of angular acceleration gain coefficient was put forward. The relation of gain coefficient with slip ratio and the relation of adhesion coefficient with slip ratio were analytically obtained. The real vehicle driven on the road was tested to verify the above study. The tested results show that the changing trend of angular acceleration gain coefficient and adhesion coefficient in slip process of driving wheels is consistent. Each coefficient has peak point, which corresponds with the optimized slip ratio.
