عنوان مقاله [English]
The main part of submarine preeesure hull is made of reinforced cylindrical shell which usually divided by bulkhead to some compartments. In this article we investigate the efecct of bulkhead on vibration of submarine pressure hull. To do this, first we have analyzed the free vibration of reinforced cylindrical shell with ansys software and then the results have been compared with analytical and experimental results. After confirmation of the results, by adding the bulkhead to the shell we have considered the effect of bulkhead on vibration of the shell.
