Considering the particle's velocity and acceleration of a cylindrical metal sample during the process of forging,the author has established the differential equations of the hammer's velocity and acceleration in rela tion to the compression rate,and has obtained the numerical solutions by a FORTRAN program. Comparing the solutions with the testing results, the author has discussed the effects of every parameter on the forging.

本文计入了圆柱体在镦粗过程时质点的速度和加速度的影响,建立了模具的速度、加速度与试件压缩比各之间的微分方程,编成计算程序,在微机上实行计算,监将计算结果同实测作了对比,讨论了各个参数对锻造成形的影响。所编程序比较简单,有一定的通用性,可将模具的动能,质量、初速度、初加速度、试件的尺寸、流动应力以及试件对模具的摩擦系数等参数随时变换,应用比较方便。也可以根据试验得到的变形终了高度反算出不同打击速度下的流动应力值。

In this article, the author gives a simple method of calculating the impulsive stress response of the pillar form frame of a high speed forging hammer while deformation of the forging sample is very small during the farging period. The solutions are comparatively comformable to the testing results.This computational method is also applicable to frames with box cross section.The contents of this article are supplements to several computational methods established by the author for the strength analysis...
