基于环形件轧制过程中体积不变原则,建立了导向辊运动轨迹方程,并借助MATLAB软件进行求解,得到了导向辊中心瞬时x、y方向的位移及其旋转角速度ω;将计算数据导入到ABAQUS中,进行外台阶截面环形件轧制成形的数值模拟。结果表明,采用所提出的方法可以较精确地确定导向辊运动;该研究结果为保证轧件质量实时合理地控制导向辊的运动奠定了理论基础。 Based on the principle of volume invariance during ring rolling, the trajectory equation of the guide roller was established and solved by MATLAB software. The displacement and the angular velocity ω of the instantaneous center of the guide roller in the x and y directions were obtained. In ABAQUS, the numerical simulation of the ring forming of the outer stepped section was carried out. The results show that the proposed method can accurately determine the movement of the guide roller. The results of this study provide a theoretical basis for ensuring the quality of the rolling material to control the movement of the guide roller in real time and reasonably.
