采用三维刚塑性有限元法对四种径向精锻变形道次的变形分布进行了数值模拟计算;结合模拟实验讨论了变形分布对锻材组织及质量的影响。结果表明,变形分布的均匀性和渗透性的结合是获得高质量锻材的必要条件,工艺中应给予考虑。 The three-dimensional rigid-plastic finite element method was used to simulate the deformation distribution of the four kinds of radial precision forging deformation passes. The effect of deformation distribution on the structure and quality of the as-rolled material was discussed with the simulation experiment. The results show that the combination of the uniformity of deformation distribution and permeability is a necessary condition for obtaining high quality forgings and should be considered in the process.
