Numerical Simulation and Analysis for the Strain Distribution of Four Kinds of Radial Forging

摘要: 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。

Abstract: The strain distributions of four kinds of radial forging processes have been simulated by rigid-plastic FEM.Together with the experimental results, the effect of strain distribution to the structure and quality of the forging products has been discussed.And, the necessory condition to obtain high-quality forging product has been presented.
