Determination of cylinder liner free vibration frequencies in diesel marine engines

Valishin A., Adamkiewicz A.

Journal of Polish CIMAC

2012

Vol. 7, no 2

227-233

This article presents a method to determine free vibration frequencies of cylinder liners in marine gas engines based on the power method. The cylinders were treated as thin-walled tubes getting distorted because of a long term variable load. The assumptions for the model have been made, mathematical procedure has been shown as well as a description of cylinder free vibration types. The final description of free vibrations was related to the way in which the cylinder was mounted searching for a minimum free vibration frequency.
