摘　　要：采用三维绘图软件绘制了行走轮产品的实体模型,设计和制定了其浇注系统及工艺参数。运用华铸CAE数值模拟软件对铸件及其浇注系统进行网格剖分,模拟铸件的充型和凝固过程,分析缩孔、缩松产生的位置与原因。结果表明,根据模拟结果,优化了浇注系统,合理改进了铸造工艺,并严格控制操作过程,缩短产品的开发周期。The 3 D drawing software was used to draw the solid model of the walking wheel product,and the pouring system and process parameters were designed and formulated.The CAE numerical simulation software of Huazhu was used to mesh the casting and its pouring system,simulate the filling and solidification process of the casting,and analyze the location and cause of shrinkage cavity and porosity.The results show that according to the simulation results,the casting system is optimized,the casting process is improved reasonably,and the operation process is strictly controlled to shorten the product development cycle.
