利用数学软件MATLAB,对导向辊运动过程中的角速度、水平(X)、竖直(Y)方向的位移进行了计算,将获得的计算数据导入到通用模拟软件ABAQUS中,并利用其对4.6m大直径环件径、轴向轧制成形过程进行成形仿真。结果表明,合理的导向辊运动控制实现了大型环件的径、轴向轧制,模拟结果显示,应力、应变分布及端面鱼尾形状等符合实际。 The mathematical software MATLAB was used to calculate the angular velocity, horizontal (X) and vertical (Y) displacements during the movement of the guide roller. The calculated data were imported into the general simulation software ABAQUS. Large diameter ring diameter, axial forming process simulation of the forming process. The results show that reasonable guide roller motion control can achieve the diameter and axial rolling of the large ring, and the simulation results show that the stress and strain distribution and the shape of the fish tail are in line with the actual situation.
