摘　　要：运用专业铸造模拟软件Procast对某型发动机进气管进行了数值仿真分析。建立了砂型铸造进气管充型凝固过程中的几何模型和有限元模型。通过对运行参数、边界条件等设置,实现了基于Procast软件对其整个铸造过程模拟。在给定的铸造工艺方案下,充型平缓,凝固顺序遵循顺序凝固原则,没有出现缩松、缩孔现象,满足浇注条件。结果表明,此次铸造工艺设计合理,可依据模拟结果进行实际生产。Procast soft-ware was used for the numerical simulation analysis of a type of engine intake manifold. The geometrical model and finite element model in the filling and solidification process were established. By setting operating parameters and boundary conditions, the simulation of entire casting process was achieved based on Procast software. Under the given casting process scheme, filling is gentle, solidification order follows the principle of directional solidification without shrinkage porosity and shrinkage cavity defects in the casting process. The results show that the design of casting technology is reasonable, the practical production can be conducted according to the simulation results.
