摘要

以风力发电机轴承座为研究对象,对风力发电机轴承座铸件进行铸造工艺设计,应用有限元软件ProCAST对轴承座的铸造过程进行模拟,反映了铸件充型和凝固过程的实际情况,预测了铸件缩孔、缩松缺陷产生的部位。根据模拟结果,分析缺陷产生原因,对铸件的铸造工艺方案进行优化。结果表明,优化方案有效地减少了缩孔、缩松缺陷,降低了废品率和生产成本。
        Taking a wind turbine bearing pedestal as the research object, the casting process of the wind turbine bearing pedestal was designed. The numerical simulation of the casting process of bearing pedestal was carried out by using Finite element software ProCAST, which reflected the actual situation of casting filling and solidification process. The locations of shrinkage cavity and shrinkage porosity were predicted. According to simulation results, the reason of defects was analyzed,then the casting process was optimized. The results show that the optimized process effectively reduces the shrinkage cavity and shrinkage porosity defects, and the rejection rate and production cost reduce.
