  1. Using 2 - d strip method and the high - speed slender body theory, the heaving motion responses in regular wave of ship with combined appendage are computed. the results are compared with the results of naked ship hull, and the anti - pitching effect of combined appendage is validated. a method of optimizing the seakeeping is provided from the aspect of the ship hull

    因此本文針對船舶耐波性能的優化,提出了一種減縱搖組合附體,將半潛艏和艏鰭安裝在常規單體船上,初步闡述了半潛艏和艏鰭的水動力作用機理,並按照二維切片法和高速細長體理論計算了加裝組合附體后,船舶在規則波中的垂向穩態運動響應,與裸船體的結果進行了比較,驗證組合附體的減搖效果,從船體本身出發提供了?種優化船舶耐波性的方法; 3
  2. Secondly, the non - linear model of ship motion was studied. the non - linear term and the term related to pitching velocity are referred to disturbance of the system to get state feedback designed mathematic model of the rudder / fin joint control system. the non - linear rudder / fin joint control system - designing problem was transformed into disturbance attenuation linear system designing problem, which uses quadratic performance as object function

    為了得到船舶舵鰭聯合控制系統的狀態反饋h ~設計的數學模型,把非線性項及與橫蕩速度相關的項也看作是對系統的擾動,把非線性船舶舵鰭聯合控制系統設計問題化為以二次型性能指標為目標函數的干擾抑制的h ~線性系統設計問題。
  3. The coordinate transformation technology is adopted to compensate real time attitude angles of the swinging ship on the azimuth and pitching axis of tracking equipment in order to stabilize los and improve precision

    故採用坐標變換技術,在跟蹤設備的方位和俯仰軸上對船搖姿態角進行實時補償,達到視軸穩定、提高精度的目的。
