A design of T-foil and trim tab for fast catamaran based on NSGA-II

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