摘　　要：借助大型商用有限元软件MSC.Marc,采用隐式静力和隐式动力有限元算法,对GCr15棒线材的粗轧过程进行了热力耦合有限元模拟,模拟采用生产实际中的轧制参数。2种算法的出辊速度、温度场和平均轧制力模拟结果基本一致,温度场模拟值与实测值的比较证明了这2种算法的可靠性。实际模拟时,隐式动力学算法计算时间少于隐式静力学算法,效率较高。The implicit static and implicit dynamic methods were used to simulate the rough rolling process of GCr15 rod and wire using the commercial FEM software MSC. Marc. The actual parameters of production line were used in the two FEM models. The speed at exit, temperature distribution and average rolling force simulated by implicit static method was in good agreement with that simulated by implicit dynamic method. The reliability of the two models was testified by comparison between simulated and measured temperature distribution. The implicit dynamic method has higher efficiency than the implicit static method due to less computation time.
