VLCC概念设计数学模型

Mathematical models for VLCC's concept design

通过收集ＶＬＣＣ总体性能资料和设计变换，依据船舶总体设计原理，运用数理统计分析的多元逐步回归方法建立船舶总体性能数学模型；包括主尺度、船形系数、重量、容积、稳性、吨位和干舷等．模型反映了ＶＬＣＣ船型最新发展并符合ＭＡＲＰＯＬ７３／７８公约的附则１的１９９２年修正案对ＶＬＣＣ船型的最新规定，能够满足ＶＬＣＣ船型论证和概念设计的精度要求。

Mathematical models, used for VLCC's concept design, are constructed with multi variable stepwise regression analysis method in mathematical statistics area, based on the information collected from over seventy VLCCs built since 1978. The formulae can be applied to determine the principal dimensions, coefficients, lightweight, capacity, initial stability, gross and net tonnage, freeboard of a VLCC of which has the double hull structure required by MARPOL 73/78 regulation and its amendment in 1992, in the concept design stage. Some calculation results are given out as application examples.
