基于Caloomp的复合铝棒铸造有限元仿真
|
摘要
为了获得力学性能优良、内部组织细密的复合铝棒(6061铝合金芯材及AA3104铝合金表材),分析了其铸造复合原理及工艺。运用Caloomp软件建立了复合铝棒铸造有限元仿真模型,分析了铸造过程中浇注温度、芯材浇注速度及表材浇注速度对其抗拉强度的影响。结果表明:复合铝棒在铸造过程中,浇注温度对其温度分布及抗拉强度影响较大;不同芯材及表材浇注速度对铝棒芯材及表材抗拉强度影响不同,在复合铝棒铸造过程中需选择合适的芯材及表材浇注速度。
In order to obtain a composite aluminum rod(6061 aluminum alloy core and AA3104 aluminum alloy surface material)with excellent mechanical properties and fine internal microstructure, the foundry compound principle and process were analyzed. The finite element simulation model of composite aluminum rod casting was established by using software Caloomp. The influences of different pouring temperature, different pouring speeds of the core and different casting speeds of the surface material on the tensile strength were analyzed. The results show that the casting temperature has a great influence on the temperature distribution and tensile strength of the composite aluminum rod during the casting process; the different core materials casting speed and surface material casting speed have different effects on the tensile strength of aluminum rod core materials and surface materials. It is necessary to select the appropriate materials and the casting speeds of the core material and surface material in the process of composite aluminum rods casting.
