The rolling process of rock drill steels were simulated by ANSYS/IS-DYNA.
利用ANSYS/LS-DYNA有限元分析软件,对钎钢轧制过程进行三维数值模拟,获得了三个主要轧制工艺参数对成品质量的影响规律。
Because their cross sections are almost equilateral hexagons,the equilateral hexagons rock drill steels are regarded as my research objects.
钎杆用中空钢,简称“钎钢”,截面以正六角形和圆形为主,因此本文以正六角形钎杆用中空钢为研究对象。
Finally, to validate the computational values, rock drill steels rolling experiments were carried out by using lead specimens.
利用ANSYS／LS-DYNA有限元分析软件,对钎钢轧制过程进行了数值模拟,根据数值模拟结果,得到了三个轧制工艺参数对成品质量影响的规律。
