Numerical Analysis of Force and Power Parameters in Cold Ring Rolling


Article Preview

During cold ring rolling process, the accurate prediction and analysis of force and power parameters, including roll force (RF) and roll moment (RM), is important in selecting, designing and developing the forming rolls and cold ring rolling mills. In this paper, a three-dimensional elastic-plastic dynamic explicit FE model of cold ring rolling process has been presented and validated in terms of roll force and geometry development. Based on the model, the variation laws of force and power parameters under different sizes of forming rolls (including driver roll and idle roll) and forming parameters (including the rotational speed of driver roll 1 n and the feed rate of idle roll v ) have been revealed by comprehensive numerical simulations.
