摘要
采用商用软件DEFORM用刚塑性有限元理论对GFM精锻锻透性进行了仿真研究,确认了GFM锻不透的问题并指出锻透性最大只能达到约60％,且与摩擦条件的影响关系不大,进而得出了GFM锻透性FPE与压下率△h／R的5次方回归关系式,为GFM精锻的工艺设计提供了参考。
The problem of how to determine the forging penetration efficiency (FPE) for GFM forging, which has not been solved as yet, is tackled with rigid-plastic FEM DEFORM software. The results are as follows: 1) It is confirmed that no full FPE exists in GFM forging process, with the maximum FPE being only 60% approximately; 2) The influence of friction coefficient on FPE is very small; 3) A regression equation between FPE and reduction rate △h/R is presented.
