摘要
用上限法分析了环件开式辗扩变形,导出了辗扩力和力矩计算公式,阐述了辗扩力和力矩与辗扩进给速度的关系。根据环件辗扩实验结果,对文中的辗扩力和力矩计算公式进行了验证。
Plastic deformation in ring rollling with open groove is analysed in use of upper bound method, the expressions of roll force and torque in ring rolling are derived, and the relations of the roll force and torque to feed velocity in ring rolling are explained. The formulae of roll force and torque are verified by ring rolling experiment.
