ABSTRACT
Cruise ships have high and plump superstructures, resulting in the vibration of open areas under complex wind fields, thereby significantly impacting the comfort of luxury ships. In this paper, the typical guide rail structure in the open area of a cruise ship was selected as the research object. The influence of the fluid-solid coupling method parameters was explored based on wind tunnel tests, and the method’s accuracy was verified. The results of the whole-ship wind field were applied as the wind field input of the open area by the subdomain method. Then, wind-induced vibration analysis of the guide rail structure in the open area was carried out under different wind conditions. The results revealed that employing the turbulence model SST k-w obtained minimal error between the simulation and test, and the vibration frequency of the guide rail structure was mainly concentrated at 0.8-10.1 Hz. The most unfavorable wind angles were 0° and 120°. This study could provide a reference for wind-induced vibration prediction and comfort design of typical structures in open areas of large cruise ships.
