Numerical Simulations Supporting the Process Design of Ring Rolling Processes
In conventional Finite Element Analysis (FEA) of radial-axial ring rolling (RAR) the motions of all tools are usually defined prior to simulation in the preprocessing step.However,the real process holds up to 8 degrees of freedom (DOF) that are controlled by industrial control systems according to actual sensor values and preselected control strategies.Since the histories of the motions are unknown before the experiment and are dependent on sensor data,the conventional FEA cannot represent the process before experiment.In order to enable the usage of FEA in the process design stage,this approach integrates the industrially applied control algorithms of the real process including all relevant sensors and actuators into the FE model of ring rolling.Additionally,the process design of a novel process the axial profiling,in which a profiled roll is used for rolling axially profiled rings,is supported by FEA.Using this approach suitable control strategies can be tested in virtual environment before processing.
