非对称轧制过程的参数

本文提出了非对称轧制过程的全粘着三角形上限解模型，并建立了模型参数关系。采用约束优化的方法对变形功率进行极小化处理，确定了模型参数，进而研究了轧制条件对轧件弯曲、压下量分配等参数的影响．对轧辊速度不匹配时轧制参数的研究表明，文中方法和有限单元法分析及实验研究结果吻合。

Investigation on Parameters in Asymmetrical Rolling Process

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.
