Study on Rollers’ Angular Velocity Matching of Rolling Driven Equal Channel Angular Deformation Technology
Rollers’angular velocity matching of rolling driven equal channel angular deformation technology was investigated numerically by using finite element code DEFORM-3D. The results show that as the angular velocity of primary feeding roller is constant, the rollers’ angular velocity matching had only small influences on effective strain and output velocity, but had significant influence on torque of feeding rollers. With the decrease of angular velocity ratio of primary feeding roller to secondary feeding roller from 1.37 to 0.073, the torque of feeding rollers tend to become uniform. It was found that an appropriate selection of rollers’ angular velocity matching and friction factor can save energy consumption significantly.
