Abstract:
To control the vibration level of ships under construction, MSC Software’s Patran & Nastran modeling solutions can be used to establish a detailed finite element model of a new manned submersible support mother ship based on a line drawing, including the deck layout, bulkhead section, and stiffener distribution. After a comprehensive analysis of the ship simulation conditions, boundaries, and excitation forces of the main operating equipment, modal analysis and calculation of the ship vibration can be conducted. In this study, we calculated and analyzed the vibration response of key points in the stern area of the ship’s main deck and the submersible warehouse area under design loading working conditions. We then analyzed the vibration response of typical decks (including the compass deck, steering deck, captain’s deck, forecastle deck, and main deck) under the main excitation forces and moments (such as the full swing pod and generator sets). The analysis results showed that under DESIDEP working conditions, the vibration of each deck and key areas of the support mother ship could meet the vibration code requirements of the ship’s preliminary design (using the pod excitation and generator sets). Similarly, the vibration response of a scientific research ship under other loading conditions also met the requirements of the code and provided data support for a comprehensive understanding of the ship’s vibration and noise levels. Using actual vibration measurements, the accuracy of the vibration level simulations using finite element modeling was verified, the vibration of each area of the ship comfortably meeting the requirements of the China Classification Society.
