摘要

利用MAGMA软件分别对海豚型直升机主机匣铸件的低压铸造和重力铸造的充型及凝固过程进行数值计算

并对低压铸造方案的数值模拟结果进行试验验证。结果表明

应用低压铸造有利于减少主机匣铸件的氧化夹渣、缩孔及缩松等缺陷。

Abstract

The MAGMA software was used to numerically simulate and calculate the filling and solidification process of main housing of dolphin helicopter in low pressure casting and in gravity casting.Experiments were conducted to confirm the simulation results of low pressure casting.The results show that low pressure casting is beneficial for the decrease of oxidized slag inclusion and shrinkage porosity.
