摘要
在分析开式模锻型腔充满阶段的应力与应变特点的基础上,提出一种计算开式模锻型腔充满阶段的变形力分布的工程计算方法,并用此方法推导出几种典型模锻情况下的变形力分布函数式。经实验验证,变形力分布的计算结果与实测值基本吻合。
Based on the analysis of the stress and strain of cavity during the full filling period in closed-forging die,this paper proposes an engineering calculation method for the stress distribution,from which a functional formula of stress distribution for some typi- cal die-forging cases has been deduced.The result of stress distribution is almost indentical with the test result.
