夹持式镦粗过程夹紧力的分析研究

The analysis and study of clamping force during forging reduction of the nipping type

应用滑移线理论和金属的塑性变形理论 ,分析研究圆柱体镦粗过程中的夹紧力的计算方法 ,并与试验结果进行比较。

Based on the theory of slip line and plastic deformation of metal,the clamping force for forging reduction of cylinder is analyzed and studied.And the result of evaluation is well consistent with that of experiment.
