摘　　要：为了解决1.5 MW风力发电机组轮毂球墨铸铁件在铸造过程中容易产生缩松缩孔缺陷的问题,采用计算机数值模拟技术对轮毂的浇注系统进行优化设计分析。研究了轮毂球墨铸铁件的凝固特点,明确了铸件产生缺陷的原因,利用三维造型软件和铸造模拟软件对风力发电机轮毂铸件凝固过程的温度场进行模拟,得出了铸造风机轮毂的优化工艺方案。模拟结果显示,优化工艺可以明显地改善风机轮毂在铸造过程中产生的缩孔缺陷。For solving the problem of shrinkage porosity in 1.5 MW wind turbine hub casting,casting optimization of getting system for the wheel hub has been analyzed with the numerical simulation technology to reduce the volume of shrinkage porosity.The solidification characteristics of ductile iron castings has been studied,and the reasons of shrinkage porosity in 1.5 MW wind turbine hub has been cleared,the casting process optimization and the temperature field simulation has been carried out with 3D software and casting numerical simulation software.The simulation results show that the shrinkage defects of 1.5 MW wind turbine hub have been significantly controlled since the optimized casting processes are used.
