考虑轧辊弹性压扁的铝带冷轧轧制力有限元模拟研究

Finite Element Simulation Study of Aluminum Strip Cold Rolling Force Considering Roller Elastic Squashing

在冷轧轧制中轧辊会产生弹性压扁,对轧制力影响较大。本文以ANSYS/LS-DYNA为分析软件,将轧辊辊身设置为弹性体,模拟分析了刚性轧辊轧制力、弹性轧辊轧制力、不带张力、带张力等情况下的轧制。从分析中,可以看出轧制力的影响规律。可以指导生产,降低试验成本,具有一定理论意义和实用经济价值。

Elastic squashing will occur for roller during cold rolling, which would affect the rolling force. Rolling process is simulated under the conditions of rolling force of rigid roller, elastic roller and rolling with or without tension based on the software of ANSYS/LS-DYAN and regarded roller as elastomer. Effect law can be obtained from the analysis. Thus this can instruct production, and theoritcal meaning and actual economic value are gotten.
