The research object of this article is a SWATH, and numerical calculations were conducted on a SWATH model under various operating conditions using viscous CFD software STAR-CCM+. Explored the hydrodynamic performance of SWATH in still water and waves, as well as their longitudinal motion stability at different speeds. By observing and analyzing the time history curves of longitudinal motion at different speeds, it was determined whether the ship had lost its longitudinal motion stability under various speed conditions, and the motion response of SWATH on regular waves was studied.

摘要

The research object of this article is a SWATH, and numerical calculations were conducted on a SWATH model under various operating conditions using viscous CFD software STAR-CCM+. Explored the hydrodynamic performance of SWATH in still water and waves, as well as their longitudinal motion stability at different speeds. By observing and analyzing the time history curves of longitudinal motion at different speeds, it was determined whether the ship had lost its longitudinal motion stability under various speed conditions, and the motion response of SWATH on regular waves was studied.
