摘要
为降低环件在轧制过程中的偏摆振动,实现环件的平稳轧制,基于ABAQUS软件,编写VDISP子程序,实现在数值仿真中对导向辊的控制,并根据不同的导向辊控制方式,分别建立无导向辊、导向辊固定、导向辊随动和子程序控制导向辊运动4种模型。采用控制变量法,对以上模型的偏摆-时间曲线、尺寸-时间曲线以及能量-时间曲线进行分析。结果表明:所建立的环件轧制自适应控制系统能有效降低环件轧制过程中的偏摆振动问题,提高环件轧制过程的稳定性,偏摆量基本控制在0.4 mm范围内,同时可将轧制过程中产生的大部分能量用于辗扩变形。
In order to reduce the deflection vibration of ring during the rolling process and achieve the smooth rolling of ring,a VDISP subroutine was written based on software ABAQUS to realize the control of guide roller in the numerical simulation,and according to dif-ferent guide roller control methods,four modes were established respectively,namely,no guide roller,guide roller fixed,guide roller fol-low-up and subroutine controlled guide roller movement.Then,using the control variable method,the deflectionl-time curve,size-time curve and energy-time curve of the above models were analyzed.The results show that the established adaptive control system for ring roll-ing can effectively reduce the deflection vibration problem during the ring rolling process and improve the stability of the ring rolling process.The deflection amount is basically controlled within the range of O.4 mm,and most of the energy generated during the rolling process can be used for the rolling and deformation.
