有限元模拟技术在主体锻造工艺设计中的应用

采用Forge 2D/3D锻造有限元模拟软件,模拟和分析了大型锻件主体的锻造环境和变形过程;讨论了锻件温度、模具设计、锻造设备等因素对锻件成形的影响;分析了锻造过程中锻件应力应变、金属流动规律、缺陷预防、金属流线、锻件最终几何形状等因素;确定了下料重量、锻造能量、锻造火次、模具设计等锻造工艺设计中的重要参数,为实际生产中锻造工艺的制定提供了依据。

Application of finite element simulation in case forging technology design

Using Forge 2D/3D forging finite element simulation software,the forging environment and deformation process of large forging case were simulated and analyzed.The influences of forging temperature,die design,forging equipment and other factors on the forging blank were discussed.The stress and strain,rule of metal flowing,forging flaw,metal lines,the final geometrical shape of finished forging,etc.during forging were analyzed.The important parameters,such as the weight of cropping,forging energy,heating times,die design,etc.in forging technology design were determined,which provide a reference for forging technology design in actual production.
