摘要：

为解决立式双驱轧制大型筒形件过程中稳定性差而造成的圆度缺陷等问题，首先建立了由筒形件长大速度驱动的、能够实现多轧辊协调运动的筒形件立式双驱轧制有限元智能仿真模型；其次提出了3种双主辊转速匹配的方案：轧制开始时刻匹配、轧制中间时刻匹配以及轧制结束时刻匹配；最后，通过有限元模拟探讨了3种方案对轧制过程稳定性和筒形件圆度的影响规律。结果表明：在3种方案的轧制过程中，成形稳定性和筒形件圆度均为先变差后变好。此外，相较于轧制开始时刻和轧制中间时刻匹配，双主辊转速按轧制结束时刻匹配的筒形件的成形稳定性和圆度最好，这为大型筒形件立式双驱轧制过程的优化设计与稳健控制奠定了重要基础。

To solve the problems of roundness defect caused by poor stability in rolling process for large cylindrical parts by vertical double drive, firstly, an finite element intelligent simulation model of the vertical double drive rolling for cylindrical parts was established, in which the rolling process was driven by the growing speed of cylindrical parts and the coordinated movements of multiple rollers was realized. Secondly, three kinds of matching schemes for double main rollers rotate speed were proposed, namely, matching at the start time, the middle time or the end time of rolling process. Finally, the influence laws of three kinds of schemes on the stability of rolling process and the roundness of cylindrical parts were discussed by finite element simulations. The result shows that in the rolling process of the three kinds of schemes, the forming stability and the roundness of cylindrical parts become worse first and then better. Besides, compared with matching at the start time and at the middle time of rolling process，the forming stability and the roundness of cylindrical parts are the best when the rotate speed of double main rollers are matched at the end time of rolling process, which provides important foundation for the optimal design and robust control of the vertical double drive rolling process for large cylindrical parts.
