| Abstract: | This paper analysed the strength of a new high-power and high-effi- ciency engine block by FEM. The FEM model included the contact between the block and the main bearing cap, between the cylinder and the equivalent cyclinder head model. Based on temperature, this paper presented a new method on how to apply the pretightening force on the FEM model. This method made it easy to ap- ply this type of load on the FEM model. |
