Popis: | The deformation of ceramic shell poses a potential and uncertain threat on the dimensional accuracy of the final casting in the investment casting process. In this paper, a finite element analysis method (FEM), permafrost analysis methodology (PAM), is used to simulate the deformation of the ceramic shell in the firing process. In the PAM, the porosity and the phase transformation of the ceramic shell in the firing process are taken into consideration. The comparison of simulation and experimental results indicated that the PAM can predict the deformation of the ceramic shell with high accuracy. The work of this paper presents a new approach to simulate the deformation of the ceramic shell, and there is a great significance to improve the dimensional accuracy of the final casting in the investment casting process. |
