摘要
以弯曲塑性铰理论为基础,建立了普旋过程毛坯起皱的分析模型。采用能量法,推导出旋压力的计算公式。由数值方法,得出临界皱波数随若干工艺参数的变化规律,分析结果与实际情况相符。
The analytical model of blank wrinkling in conventional spinning is established on the basis of the bending plastic hing theory. The calculation equation is derived according to the principle of energy method. By numerical method, the relationship between the critical wrinkle number and the process parameters has been obtained, which accords with the practice.
