摘　　要：建立了气缸套离心铸造凝固过程的数学及物理模型,阐述了离心铸造凝固的数值分析的方法,利用计算机进行数值模拟求解得到气缸套离心铸造过程中的温度场、液固相分布及缩孔缩松状况。由模拟结果总结了气缸套凝固规律,为气缸套的铸造工艺优化设计提供了数值依据。The mathematical and physical model of solidification process of cylinder liner in centrifugal casting was established for numerical analysis. The numerical simulation method for centrifugal casting solidification process was elaborated. The temperature field, the liquid-solid phase distribution and the status of the porosity shrinkage in centrifugal casting process were solved based on computer simulation. The numerical simulation results show that the automotive cylinder solidification laws could be summarized and provided a numerical basis for future optimization design of casting process.
