| Abstract: |
| In this paper a fictitious interface element method dealing with thermal resistance between casting and mold is presented, and the finite element formula is given. The contact surface between casting and mold is seen as interface element because the element thickness has nothing to do with the gap between them. The finite element analysis for the casting solidification of an alloy aluminium piston with metal mold has made in according to two ways with and without thermal resistance. The calculating accuracy using the above algorithm is much higher than that without thermal resistance. In addition to this, finite element mesh generation is easier and more general by using this method. |
