Finite Element Analysis of Engine Fixed Parts Assembling Process

In order to select the best design method for stay bolts in the diesel engine assembling process, main fixed parts of some MAN low-speed marine diesel engine were analyzed based on finite element analysis software Hyperworks. The mechanical performance of bottom, frame and cylinder under the effect of the four kinds of assembling methods was investigated. Ultimately, the best assembling process was confirmed. Results indicated that the finite element analysis model was reliable and exactly. The middle to both sides assembly was the best among the four methods.
