A Design of T-foil and trim tab for Fast Catamaran based on NSGA-II

This paper proposed a optimization design for a ride control system for fast catamaran. The ship vertical motions are predicted by 2.5d theory. The hydrodynamic characteristics of T-foil and trim tab are given, and the dynamic stability of the system is discussed. On the basis, the ride control system optimization model in regular and irregular waves are established for a specific catamaran. The optimal solution are obtained by using NSGA-II.
