摘    要:用实例介绍了一项用于铸造生产的三维模拟技术,通过对金属液充型和凝固过程的数值模拟进行铸造工艺设计,从而在计算机上实现可视铸造过程,能保证既快又省地设计一个优化的铸造工艺.与传统的模数法,经验和试错的工艺设计不同,本模型是用铸件的凝固时间计算补缩系统.从一个铸件凝固模拟开始,根据凝固时间和被补缩的体积,计算冒口和冒口颈的尺寸和数量,再进行铸件加冒口的模拟计算,做必要的修正,直到获得满意的结果,最后根据铸件的临界壁厚、体积、充型速度和浇注温度等参数计算浇注系统.当整个系统设计完成后,模拟计算整个充型和凝固过程以验证设计,做必要的修正,直到获得一个能生产无铸造缺陷铸件的铸造工艺,即保证一次成功生产出合格铸件,节约了时间和成本.

关 键 词:模拟  浇注系统  补缩系统  凝固时间

Abstract:This paper presents a 3D simulation technology to design the feeding and gating systems,and simulate mould filling as well as solidification.While the traditional design was based upon pen and paper calculations(modulus),experiences and guesses,this technology enables to conduct a fast and inexpensive virtual design and verify the effect of any change,and finally resulting in an optimal casting configuration.The underlying model is based upon the solidification time of the casting to calculate the feeding s...
Keywords:simulation  gating system  feeding system  solidification time
