Experimental Investigation and FEM Simulation on Material Behaviors of Cylinder with the Rotating Flat Die

Abstract:

The study aims at exploring the effects of rotating compression forming on the material behaviors of cylinder. The experiments have been carried out under various angular velocities to realize the flow stress, the compression force, the rotating torque, the grain size, and the hardness. Furthermore, the FEM simulation is also performed to compare with the experiments. From the experimental results, as the angular velocity increases, the compression force and the grain size decrease, but the rotating torque and the hardness increase. The results can provide the industry as the reference.
