邮轮概率法破损稳性评估方法中要求计入A级防火分隔带来的进水中间阶段的影响。然而实际工程实践中发现,中型邮轮布置中存在大量A级分隔(如A级舱壁、甲板等),如果以遍历的方式考察计算这些A级边界,则会导致生成的破损工况数量过多,超出常规计算机的计算能力,无法顺利得到计算结果。以某中型邮轮实船为例,给出A级分隔的简化处理策略,并通过对比计算验证该组策略的合理性,旨在为邮轮设计者提供一种高效的设计参考方法。 相似文献

[Objective]Aiming at the problem of too many influencing factors and too little reference data for determining the dimensions of medium-sized cruise ships in the concept phase, a simplified multi-objective optimization method based on the fitting of dimensions and performance is proposed. [Method]First, the dimension relations of medium-sized cruise ships are analyzed and the influence of the latest SOLAS requirements used to determine the optimization range. Second, the influence of cruise ship dimensions on space, resistance, stability and seakeeping are analyzed. Next, based on the principles of genetic algorithms, a multiobjective optimization algorithm with high robustness and high engineering adaptability is determined to establish a multi-objective optimization model for the concept design of medium-sized cruise ships. Finally, the Pareto solution obtained by multi-objective optimization is analyzed to provide initial references for determining the dimensions of the target cruise ship. [Results]Implemented via a genetic algorithm, the optimization program proposed herein is applied in the concept design of a medium-sized cruise ship in order to optimize the initial dimensions, thereby achieving the expected outcome of providing reasonable initial dimensions for cruise ship design. [Conclusion ] The proposed simplified multi-objective optimization model can provide feasible initial dimensions for medium-sized cruise ships in the concept phase. As the Pareto solution obtained by multi-objective optimization has different focuses such as resistance and stability, the most suitable solution needs to be selected according to the design object. © 2023 Chinese Journal of Ship Research.
