Multi-stages necking process and mechanism of precision thin-walled can

  • 摘要: 基于薄壁精密罐的多道次缩口工艺,分析了各道次缩口材料的变形行为,对首道次缩口与后续道次缩口进行区分,给出在不同道次缩口中缩口入模角的定义,探讨了各道次间缩口行程的控制规律,并利用有限元数值模拟进行了验证,采用专用实验设备所获得的实验结果也证实了该规律,决定了不同道次解析分析的基础不同;基于主应力法推导出了不同道次缩口载荷计算公式,证实各道次缩口工艺中最佳入模角的存在,载荷计算结果与实验结果较为吻合,并计算得出缩口载荷随凹模入模角的变化规律.
