縱搖角 的英文怎麼說
中文拼音 [zōngyáojiǎo]
縱搖角
英文
angle of pitching-
On the basis of cybernetics through forecast roll and pitch of a ship and by adjusting the object ' s space position and keep its horizontal state without limit of actual sea state according to the control rules with the predictive value of ship ' s roll angle and pitch angle
應用控制理論通過預測隨機海浪擾動下船舶的橫搖、縱搖運動的搖角值，按照所設計的控制規律實現在不受實際海況限制的情況下調整船上物體的空間位置，使此物體保持水平狀態的目的。This paper applies ittc single - parameter ocean wave spectrum to simulate a random long - crested ocean wave according to statistics superposition theory and real - time simulate disturbance on the ship by random wave. it simulates roll and pitch of the ship in random wave in the time domain and gains roll angle ( t ) and pitch angle ( t ) signal of ship rolling movement
本文根據統計疊加理論，採用ittc單參數標準海浪譜模擬模擬實際的長峰波隨機海浪，進而實時模擬長峰波隨機海浪對船舶的隨機擾動，對船舶在海浪中的橫搖和縱搖運動進行了時域模擬，得到船舶搖蕩運動的橫搖角信號（ t ）和縱搖角信號（ t ） 。For the dynamic process of ship rolling movement, this paper analyses its dynamic date with time series analysis method and brings up this system ' s the most excellent autoregressive model ( ar model ) according to least aic criterion ( akaile, information criterion ). it reveals the regular pattern of ship rolling movement and forecasts the future value of roll angle and pitch angle, then transforms it to adjusting value of object and adjusting it according to appropriate control rules
對于船舶搖蕩運動這一動態過程，採用時間序列分析的方法，建立系統的自回歸模型（ ar模型） ，並根據最小aic信息量判定準則保證建立的系統模型為最優化模型。利用參數模型的方式對船舶橫搖、縱搖運動的動態數據進行分析處理，揭示船舶搖蕩運動的規律，預測船舶橫搖角、縱搖角的未來值。In some makes of engine the helically splined coupling is not used and the angular displacement of the shafts is effected by centrifugally actuated devices of the swinging link or inclined plane type
在一些發動機的製造中，並不使用螺旋式花鍵套管，通過搖桿或斜面型的偏心操縱裝置，曲軸相位角起到同樣作用In the end the predicting model is used in watercraft motion modeling and predicting, and the auhor analyzes the result of simulating. the result indicates that this ap $ j $ ifgx9 @ 1 % & itx means is reasonable and feasible and gains the satsfactory pmpose
最後將此模型應用於艦船縱搖運動的極短期預報，並從統計理論的角度對模擬結果進行了分析，分析結果表明該方法是合理可行的，確實提高了預報精度，加長了預報時間。With the disturbance of random wave the ship will inevitably roll and result in the ship ' s incline, especially, for small ships which the most obliquity of the ship is likely to reach above degree 15. in the actual combat the rolling movement of the ship will result in difficult control of the artillery for the artillerymen on the ship, reduce the artillery ' s probability of shots, and affect the power of the artillery by direct control of the object ( artillery ) fixed on the ship it can be kept horizontal state all the time
尤其是對大量的小型艦船，船體的最大傾角甚至可達到15以上。在實戰中，船舶的搖蕩將造成炮手對船載火炮的操縱性能降低，降低火炮的發射命中率，影響到船載火炮威力的發揮。通過直接控制固連于船體的火炮，使其始終保持在水平狀態，可以提高實戰中火炮的操縱性能，提高火炮的命中率。分享友人
