摘　　要：通过对钛合金薄壁弯管的结构进行分析,利用三维软件UG对其进行几何建模,采用ProCAST软件对顶注式、雨淋式和底注式三种浇注方案熔模铸造工艺进行了数值模拟,研究对比其在三种浇注方案下铸件的充型及可能出现缺陷的情况。得出在底注式浇注工艺方案下铸件的整体质量最优的结论,并对其进行了试验验证,获得无疏松和夹杂等缺陷的优质铸件。Through analyzing the structure of the titanium alloy thin-wall bend pipe,3D software UG was used to conduct geometric modeling,and ProCAST software was used to numerically simulate the investment casting process of three pouring schemes,top pouring,rain pouring and bottom pouring,to study and compare the filling and possible defects of the castings under the three pouring schemes.It concluded that the overall quality of castings under the bottom casting process was the best,and it was verified by experiments,and the high-quality castings without porosity and inclusion were obtained.
