Through establishing the neural network model to predict v-ribbed belt material property

and the material property is applied to the finite element analysis model

the V-ribbed belt pulley contact problems are analyzed.The results show that the neural network model can effectively predict the characteristic of rib composite rubber material.The ribbed contact pressure is different in different contact points

and the ribbed contact pressure gradually increase from under the floor to the rib.With the increase of the angle

the contact pressure of ribbed is increased dramatically after the first decreases sharply after smooth increase.The V-ribbed belt under the condition of high temperature and deep into the pulley groove

the velocity loss is bigger

the transmission efficiency is lower.
