【摘要】 本研究提出了一个小水线面双体船纵向运动控制系统的数学模型,建立了小水线面双体船纵向运动控制系统试验平台。开展了前后鳍静态和动态水动力学特性试验,证实了设计的前后鳍具有对船的控制能力;然后分别进行了无控前后鳍和单前鳍控制船模在不规则波中的耐波性试验。试验结果表明,前后鳍控制的实船在波高5m平均海浪周期9．5see的海区作业时,升沉和纵摇有效值分别下降了13．8％和35．2％,单前鳍控制的实船的升沉和纵摇有义值分别下降1．5％和17．4％。更多还原

【Abstract】 A mathematical model of longitudinal motion control system of SWATH was presented and its experiment platform was established in this paper. First, static and dynamic hydrodynamic characteristic of fore fins and aft fins were conducted and verified that they could control SWATH effectively. Second, the model sea-keeping experiments of non-con-trolable SWATH in irregular wave were conducted. Then the model sea-keeping experiments of controlable SWATH in irregular wave were conducted. These experiments results show that the signifcant height of heave and pitch of full scale SWATH are reduced 13. 8% and 35. 2% respectively by preliminary optimizing controlable fore and aft fins in irregular wave, 1.5% and 17. 4% only by controlable fore fins.更多还原
