【摘要】：小水線面雙體船獨特的片體結構使橫向波浪載荷成為其最危險的波浪載荷。在小水線面雙體船設計初期,片體間距的確定十分重要。本文根據(jù)工程中某小水線面雙體船的相關資料,對其正常裝載狀態(tài)、滿載狀態(tài)和最大排水狀態(tài)3種裝載狀態(tài)進行波浪載荷預報。采用三維頻域計算方法,對不同片體間距的小水線面雙體船進行波浪載荷預報,給出各橫向波浪載荷分量的RAO值和長短期預報值,并將波浪載荷的長期預報值與ABS和CCS中載荷的規(guī)范值進行比較。通過比較不同片體間距小水線面雙體船的載荷預報值,得到小水線面雙體船片體間距對其波浪載荷的影響特性,為小水線面雙體船的初步設計提供依據(jù)。
[Abstract]:The transverse wave load becomes the most dangerous wave load in the waterline catamaran due to its unique lamellar structure. In the early stage of waterline catamaran design, it is very important to determine the space between the pieces. According to the relevant data of a small waterline catamaran in engineering, the wave load prediction is carried out for its normal loading state, full load state and maximum drainage state. In this paper, the wave loads of small waterline catamaran with different body spacing are predicted by using three-dimensional frequency domain calculation method. The RAO values of each transverse wave load component and the long and short term prediction values are given. The long-term prediction values of wave loads are compared with the normal values of loads in ABS and CCS. By comparing the load prediction values of small waterline catamaran with different spacings, the influence characteristics of small waterline catamaran spacing on wave loads are obtained, which provides the basis for the preliminary design of small waterline catamaran.
