中文摘要：
为热戒指滚动的方法建模的新 FE 被解决象接触和热边界条件那样的关键技术介绍，运动在指南转动上控制，并且集中可伸缩。方法有下列特征：1 ) 有弹性塑料的动态明确的途径被采用而不是静态的含蓄的途径解决这个过程以便没有牺牲计算精确性，极大地改进计算效率；2 )coupledthermal 机械的效果与常规等温的假设对比被考虑，它是更实际的；3 ) 与简化 2D 或本地 3D 戒指模型，相对照， Ml 3D 戒指被建模模仿这个过程。基于为方法建模的 FE，热平凡戒指滚动的二个盒子在 FEA 软件 ABAQUS/Explicit 被模仿。模拟结果与试验性的大小相比，在他们之间的好协议关于材料流动和戒指的温度分发被观察。
英文摘要：
A new FE modeling method of hot ring rolling was presented by solving keytechnologies such as contact and heat boundary conditions, motion control over guide rolls, and massscaling. The method has the following features: 1) the elastic-plastic dynamic explicit approachinstead of the static implicit approach is adopted to solve the process so as to greatly improvecomputational efficiency without sacrificing computational accuracy; 2) the coupledthermal-mechanical effect is considered as opposed to the conventional isothermal assumption, whichis more practical; 3) in contrast to the simplified 2D or local 3D ring model, the Ml 3D ring ismodeled to simulate the process. Based on the FE modeling method, two cases of hot plain ringrolling are simulated in the FEA software ABAQUS/Explicit. The simulation results are compared withthe experimental measurements and the good agreement between them is observed regarding the materialflow and the temperature distribution of the ring.
