摘　　要：针对油膜轴承合金层铸造质量问题,运用ProCAST对其离心铸造过程进行数值仿真研究,优化离心铸造模型和工艺参数。仿真结果表明:改进后的模型可提高充型速率,降低凝固速率,减少缩孔缩松缺陷。通过分析不同浇铸温度和预热温度的仿真结果,得到了适用于该轴承合金层的最佳工艺参数,以此来提高轴承合金层铸造质量,为其离心铸造工艺优化提供科学依据。Aiming at the casting quality problem of oil-film bearing alloy layer,the centrifugal casting process was numerically simulated by ProCAST,and the centrifugal casting model and process parameters were optimized.The simulation results show that the improved model can increase filling rate,decrease solidification rate,and reduce shrinkage porosity defects.By analyzing the simulation results of different casting temperatures and preheating temperatures,the optimum process parameters of the bearing alloy layer were obtained,in order to improve casting quality of bearing alloy layer,and provide scientific basis for the optimization of centrifugal casting process.
