Design and analysis of heavy suspended floats for wave gliders
This study focuses on the design of a heavy suspended carriage scheme for wave gliders,particularly on optimizing the main dimensions and side layout out of the float.Through detailed analyses of the float pitching,heaving,and rolling motion responses,we sought to enhance the stability of a wave glider.The accuracy of our simulations was validated through sea experiments.Results showed a 95.45%statistical probability that the float's rolling angle remains within 15° under irregular wave conditions with a height(H)of 1.25 m and a period(T)of 5.6 s when the transverse and longitudinal distances of the side float are 0.63 and-0.525 m,respectively.The addi-tion and optimization of the side layout can effectively improve the float's rolling motion performance.Furthermore,this design solves the problem of capsizing of wave gliders carrying heavy suspended loads,although it increases the pitching motion of the float.
