The Effect of Engine Room Location of a High Speed Craft on Global Natural Frequencies
Author(s):
Abstract:
The request for ships and vessels with higher efficiency, higher speed, less weight and also less cost, by shipyard industry, is highly depended on structural design. The vibration of structures, as one of the related phenomena to the structure of a ship, cause to fatigue in components and decreasing their efficiency. As the vibration will cause to destroying effects, studying the vibration of the ships is a critical affair. It is possible to optimize the place of equipment of a ship by knowing the natural frequencies of that ship. In this study, the modal analysis is done on a high speed craft that is designed based on the ABS rule, by using MAESTRO software and finite element method. One of the other analysis is done in this study, is the effect of engine room location of craft on global natural frequencies., that will be done by changing in engines, and generators placements in defined areas. Finally, due to the validation of the study, the experimental results of the model will be compared with the numerical results which are calculated by MAESTRO software in the vibration lab.
