摘　　要：基于DEFORM有限元软件建立了钛合金棒材三辊斜轧过程的有限元模型,并对整个轧制过程进行了数值模拟分析,得到了轧件在稳定轧制阶段的应力应变场。研究结果对于控制棒材缺陷,提高轧制效率具有重要意义。The finite element model of three-roll screw rolling process for titanium alloy bars was established and the whole rolling process was numerically simulated based on the DEFORM software. The stress and strain fields of the rolled piece in the stable rolling stage were obtained. The research result has an important significance for controlling the bar defects and enhancing the rolling efficiency.
