T型翼控制船舶在波浪上纵向运动的数值研究
Numerical research on control of longitudinal motion of ship in waves by T-foil
摘要
Abstract
[Objectives]A T-foil with an active control system can provide higher lift force and improve the seakeeping of a ship. It is necessary to calculate the anti-vertical motion effect with the different control signals.[Methods]The motion responses of the Wigley model in different wavelengths among three different Froude numbers are obtained via the slender body theory,and the lift force model of a T-foil is established.The torque control is used to obtain the governing equation of the T-foil's swing angle by analyzing the control signal. On the basis of calculating the motion of the Wigley model,the vertical motions of a ship with a T-foil in different control signals are calculated in time domain,and the attenuation effect with the three different control signals is compared. Finally the multi-signals hybrid control is studied preliminarily.[Results]The results show that the T-foil with torque control can reduce 32.43% of the heave and 57.62% of the pitch angle response extremum,and can provide a reduction of more than 61.17% in bow acceleration at peak response compared with a ship without a T-foil and with a high Froude number. The anti-vertical motion effect in the condition of Fr=0.3 is more obvious when the lift moment is controlled by the pitch angle signal,and as the speed of the ship increases,using the control signal of pitch angular velocity can obtain a lower vertical motion response.[Conclusions]In practical application the swinging angle of the T-foil can be controlled by different signals and control parameters at different speeds.关键词
