| Abstract: | In this paper, the modal analysis of cylinder block of a six-cylinder in-line diesel engine was done by ANSYS FE software. The calculation results were compared with those from the experiments and the model proved effective. The increased rigidity and reduced weight were studied by this model. The results show that the vibration of the cylinder block can be reduced by an alternated aluminum block, a ladder frame or lower case, which leads to a lower engine noise. |
