| 摘 要： | 基于流体力学传热学基本方程和有限差分方法,利用AnyCasting铸造模拟软件,采用残余熔体模数预测缩孔、缩松缺陷,用确定性模拟方法模拟微观组织。将铸造的充型凝固宏观模拟与微观组织模拟相结合,实现了铸造成型过程从宏观缺陷到微观组织以及机械性能进行完整的模拟。以某型铝合金车轮的模具设计为例,证明了该模拟方法能够指导模具结构优化,减少反复修模、试模所造成的能源浪费,提高工艺成品率。

| Abstract: | Based on hydrodynamics heat transfer theory and finite difference method, applying AnyCasting simulation software and remains melt module to forecast faults of shrinkage cavity and shrinkage porosity, applying certainty simulation method to simulate micro-scale structure. This paper combines macro-scale simulation with micro-scale simulation and realize multi-scales simulation. This simulation method can conduct die structure optimization, and reduce repeat die repair and waste of die trial energy, and improve rate of finished product. |
