舰船优化设计中耐波性计算方法的探讨

A Discussion on Seakeeping Prediction Method in Ship Optimization Design

在舰船优化设计过程中 ,要求所采用的耐波性能计算程序计算速度快而且对原始数据的完整性要求不高 ,比如设计初期往往没有完整的型值。本文总结了一个简化的耐波性能计算方法 ,包括简化的水动力系数计算方法和简化的方程。为了验证其准确性 ,将其结果与SJTU耐波性理论计算程序、DNV的商业程序以及实验进行了比较 。

During the ship optimization design,a seakeeping program that is fast enough and does not require all data of the ship is needed,since we do not have complete offsets in early stage of design.The article presents a simplified method of seakeeping prediction including a simplified method of hydrodynamic coefficient calculation and simplified equations. Comparison with the results of SJTU program,DNV program and tests indicates that the simplified method can be used in ship design.
