【摘要】:小水线面双体船独特的片体结构使横向波浪载荷成为其最危险的波浪载荷。在小水线面双体船设计初期,片体间距的确定十分重要。本文根据工程中某小水线面双体船的相关资料,对其正常装载状态、满载状态和最大排水状态3种装载状态进行波浪载荷预报。采用三维频域计算方法,对不同片体间距的小水线面双体船进行波浪载荷预报,给出各横向波浪载荷分量的RAO值和长短期预报值,并将波浪载荷的长期预报值与ABS和CCS中载荷的规范值进行比较。通过比较不同片体间距小水线面双体船的载荷预报值,得到小水线面双体船片体间距对其波浪载荷的影响特性,为小水线面双体船的初步设计提供依据。
[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.
