Study on motion of partial air cushion support catamaran in regular waves
摘要
Abstract
Motion of partial air cushion support catamaran (PACSCAT ) sailing in regular waves was studied through numerical calculation and model test .First ,pressure variation was obtained through the monitoring of air cushion pressure and compared with other parameters ,and changes rules of vari‐ous motions were obtained .Then ,numerical calculation method was used to carry out theoretical pre‐diction of the motion response ,changes of free surface and velocity vector in air cushion cabin were re‐corded ,and the calculated results and the experimental phenomena were analyzed . The outcomes show that the air pressure has opponent periodic variation to pitching and heave in waves ,but same to the acceleration .T he numerical calculation can predict the periodic oscillation of each movement rea‐sonably ,and the precision of the amplitude response of each parameter is considerable in high frequen‐cy region ,but it has large error in calculating the response of pitch ,w hich needs to improve the airbag for enhancing the accuracy .关键词
