In considering the theory of structural dynamic optimization design,a design method of the structural style of ship composite brace with rigid vibration isolation mass was studied.Two kinds of structural dynamic optimization formulations minimizing the vibration acceleration of the non-pressure hull on the restraining condition of the gross weight of the ship cabin were established:1) dynamic optimization of the sectional dimensions of the rigid vibration isolation mass in the composite brace; 2) dynamic optimization of the arranging position of the rigid vibration isolation mass.Through the optimization results,sectional dimensions and the arranging position of the rigid vibration isolation mass with better performance in reducing vibration were gained,and some reference was provided for practical engineering designs as well as enrichment of the design method of a novel ship vibration-isolation brace.
