Comfort is a key technical indicator in cruise ship design,and it is particularly important to have a cruise comfort design to prevent excessive vibration and noise that affect passenger's experience.In this regard,a structural model is created with finite element method to carry out the calculations of local modal and low order modal of the deck frame and to evaluate the structural resonance risk.At the same time,the statistical energy method is used to create a three-dimensional acoustic model of the cruise ship to calculate the cabin noise level and to analyze the cabin noise contribution.On this basis,the direction of cruise comfort control is pointed out,the design of cruise ship structure is optimized,and comfort control measures are proposed to provide reference for the subsequent comfort design and optimization of cruise ships.
