中文摘要:
      本研究针对镁合金热轧制工艺,通过协调有限元分析结果及物理试验数据,提出一种关于热轧制接触摩擦因子的确定方法,耦合多轧制工艺参数进一步拟合出其求解关系式,工艺参数包括:轧制温度,轧制速度以及压下率。在之前对AZ31B镁合金板材轧制过程轧制力预报模型及温度场数学模型建立研究的基础上,综合考虑接触单位压力及摩擦应力两方面因素的作用,对前期轧制力预报模型进行了优化重构,经确定接触摩擦作用到轧辊的压力约占整体轧制力的4.36%。

英文摘要:
      Study focused on the magnesium alloy hot rolling process. A method was proposed to determine the friction coefficient in process through the comparative analysis of finite element analysis result and experimental data. Mathematical model for solving the friction coefficient was established, combining with multi-parameters of the rolling process: rolling temperature, rolling speed and reduction rate. Based on calculation model of rolling force and temperature distribution along the contact region in hot rolling of AZ31B magnesium alloy in previous research, rolling force prediction model was optimized and reconstructed considering the normal pressure and friction stress comprehensively. The contact friction stress and its influence on rolling force with an approximate percentage of 4.36% was defined.
