Abstract：
The force of the fluid particles in the filling process of vertical centrifugal casting is analyzed.Based on the flow control equation and the motion control equation of inclusions,and based on the Huazhu CAE system,the motion tracking program of inclusions in the vertical centrifugal casting filling process is developed.A CT scan of a titanium alloy support plate casting was used to obtain the distribution information of its inclusions.The results showed that the distribution of inclusions was consistent with the distribution of the inclusions predicted by the numerical simulation,which verified the effectiveness of the numerical simulation program in this paper.Finally,the above-mentioned simulation program was used to optimize the centrifugal speed parameters of the centrifugal casting of the support plate parts,and the best centrifugal speed suitable for the support plate casting was 150 r/min.
