Numerical Simulation and Analysis for the Strain Distribution of Four Kinds of Radial Forging
-
摘要: 采用三維剛塑性有限元法對四種徑向精鍛變形道次的變形分布進行了數值模擬計算;結合模擬實驗討論了變形分布對鍛材組織及質量的影響。結果表明,變形分布的均勻性和滲透性的結合是獲得高質量鍛材的必要條件,工藝中應給予考慮。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.
