摘　　要：应用大型通用有限元分析软件ANSYS,在双金属复合铸造温度场模拟的基础上进行了三维热应力场数值模拟,得到界面的温度场,以及定量的、动态的变形及应力变化。从而有效地预测了复合层是否达到完全冶金结合以及铸造中缩孔、缩松、裂纹等缺陷出现的可能性及位置,为进一步优化双金属复合铸造工艺方案提供了科学指导。The 3-D numerical simulation of thermal stresses in bimetal composite casting has been carried out on the basis of temperature field simulation using the large-scale general finite element software ANSYS, thus achieving the temperature field of interface and the quantitative and dynamic deformation and thermal stresses. This method can predict whether the compound layer is complete metallurgical bonding and the possibility and location of defects such as shrinkage, shrinkage porosity and crack. The investigation provides scientific guidance for optimize technical scheme in bimetal composite casting.
