在环件轧制过程的有限元分析中，通常在模拟之前确定工具的运动。该过程忽略了闭环控制，闭环控制在工业过程中用于在真实的时间内控制多达八个自由度（旋转、进给速率、导辊），同时考虑到机器的性能限制以及过程演变。为了在新的模拟方法中缩小这一差距，根据FE模拟中计算的传感器值控制工具的所有运动。与机器行为相比，该过程导致更真实的模拟结果。(C)2012年CIRP。
In FEA of ring rolling processes the tools' motions usually are defined prior to simulation. This procedure neglects the closed-loop control, which is used in industrial processes to control up to eight degrees of freedom (rotations, feed rates, guide rolls) in real time, taking into account the machine's performance limits as well as the process evolution. In order to close this gap in the new simulation approach all motions of the tools are controlled according to sensor values which are calculated within the FE simulation. This procedure leads to more realistic simulation results in comparison to the machine behaviour. (C) 2012 CIRP.
