棒材的冷轧方法广泛用于制造业以获得具有复杂轮廓的工件。在这项研究中，复杂的轮廓与槽已形成的进料方法，使用两个辊。建立了一个实验系统，记录了工艺参数。用维氏硬度计测量了轧件轴向截面的显微硬度。该过程也已通过有限元计算使用Abaqus/显式代码进行了模拟。材料的行为是通过使用一个5参数的应变硬化定律，并在高应变率的热效应占。最后，实验和模拟结果进行了比较。
The methods of cold rolling of rods are widely used in manufacturing industries to obtain pieces with complex profiles. In this study, complex profiles with grooves have been formed by in-feed methods using two rolls. An experimental system was constructed to record the process parameters. The microhardness has been measured by the Vickers method in an axial section of the rolled piece. The process has also been simulated by means of finite element calculations using the Abaqus/Explicit code. The material behavior is described by using a 5-parameter strain-hardening law and by accounting for thermal effects at high strain-rates. Finally, a comparison is made between experimental and simulated results.
