Analysis of Working Parameters in Hydrostatic Extrusion by the Rigid-Plastic Finite Element Method
-
摘要: 應用剛塑性有限單元法對靜液擠壓圓棒時的主要工藝參數——變形量、模角和摩擦系數對變形過程的影響進行了分析。考慮了材料的加工硬化,經計算與實驗比較表明了兩者吻合良好。Abstract: The influence of some main working parameters——area reduction,die angle and friction coefficient on deformation procss is calculated and analysed during the hydrostatic extrusion of bar. Workhardening is also considered.The results of calculation are approximately in agreement with those of experiment.
