| 摘 要： | 借助于LS—DYNA有限元软件，对钢板的待温以及轧制过程进行了热力耦舍模拟。通过计算得到了钢板中心和表面在待温轧制过程中的温度变化曲线，待温时间对轧后钢板中心压缩应变的影响，以及经过不同待温时间后的轧制过程所需的轧制力。结果表明，如果待温时间小于60s，轧后钢板中心的压缩应变随待温时间的延长逐渐减小。

| Abstract: | Coupled thermo-mechanical finite element simulation of steel plate rolling process with temperature waiting time is carried out by means of finite element software LS-DYNA.The temperature curves of the center and surface of plate during the cooling and rolling process,influence of temperature waiting time on the compressive strain at the center of plate,and the rolling force required to complete rolling process after different temperature waiting time are obtained.The results show that,the maximum compressi... |
