Abstract:

The rolling process of cable in conduit conductor (CICC) has been simulated using the explicit dynamic finite element analysis software ANSYS/LS-DYNA. The rolling forces for different rolling passes and the influence of the rolling pass on conductor shape and conductor remainder stress have been obtained. The simulated rolling force matches the reference experimental data, and therefore the study results provide an important basis for the design of rolling equipment.

Key words: CICC, Finite element method, Numerical simulation, Rolling force, Stress

摘要：

利用显式动力学有限元分析软件ANSYS/LS-DYNA对CICC导体的轧制过程进行了模拟，得到了导体在不同轧制道次中所需的轧制力以及轧制道次对导体形状和残余应力的影响。轧制力的计算结果与参考的实验数据吻合，能为导体轧制成型设备的研制提供依据。
