非對稱軋制過程的參數

Investigation on Parameters in Asymmetrical Rolling Process

  • 摘要: 本文提出了非對稱軋制過程的全粘著三角形上限解模型,并建立了模型參數關系.采用約束優化的方法對變形功率進行極小化處理,確定了模型參數,進而研究了軋制條件對軋件彎曲、壓下量分配等參數的影響.對軋輥速度不匹配時軋制參數的研究表明,文中方法和有限單元法分析及實驗研究結果吻合.

     

    Abstract: In this paper, an upper bound solution model For asymmetrical rolling and the relationships between its parameters are presented. Based on this model, the parameters in asymmetrical rolling process such as the curuation of sheet and the distribution of reduction can be discussed with the minimization of the deformation power. The curling of sheet due to roll speed mismatch has been calculated, the agreement in results with experiments and finite element method demonstrated the efficiency of the method presented in this paper in investigating the parameters in asymmetrical rolling process.
