摘　　要：为改善传统滑行艇在波浪环境中耐波性问题,提出了一种兼具快速性与耐波性的变结构滑行艇,通过收放两侧片体实现滑单体形态与三体形态之间自由转换。为分析片体在斜浪航行中的减摇效果,采用数值方法对滑行艇2种形态在斜浪航行中的耐波性进行对比分析,结果表明:片体能够起到减横横摇作用,且其减横摇效果在单体形态的共振区域内最明显,在β_(w)=60°时,片体最多能减少70.45%的横摇幅值。In order to improve the seakeeping performance of traditional planing craft in waves,this article proposes a variable structure planing craft with both speedability and seakeeping performance.The free conversion between monohull state and trimaran state can be realized by rewinding and releasing of two demihulls.In order to analyze the anti-roll effect of the demihull in oblique waves,the numerical method is used to compare the seakeeping performance of the two states of planing craft in oblique wave sailing.The results show that the demihull can reduce roll,and the anti-roll effect is most obvious in the resonance region of the monohull.Whenβ_(w)=60°,roll amplitude can be reduced up to 70.45%.
