Simulation Ring Rolling Abaqus

Ring rolling is a specialized process typically used to manufacture parts with revolved geometries such as bearings

The driver roll has a diameter of 680 mm, and the idle and guide rolls have diameters of 102 mm The ring has an initial inner diameter of 127.5 mm and a thickness of 178.5 mm The idle and driver rolls are arranged vertically and are in contact with the inner and outer surfaces of the ring respectively

The driver roll is rotated around its stationary axis, while the idle roll is moved vertically downward at a specified feed rate

The ring is steel and is modeled as a von Mises elastic-plastic material

The analysis is run so that the ring completes approximately 20 revolutions (16.5 seconds The rigid rolls are modeled as analytical rigid surfaces The driver roll is rotated at a constant angular velocity of 3.7888 rad/sec about the z-axis while the idle roll has a constant feed rate of 4.9334 mm/sec and is free to rotate about the z-axis All other degrees of freedom for the driver and idle rolls are constrained

A friction coefficient of 0.5 is defined at the blank-idle roll and blank-drive roll interfaces Frictionless contact is used between the ring and guide rolls
