舰艇技术设计阶段的生命力分析方法

摘要

舰艇生命力分析是指根据当前船体和装备的损伤状态,计算舰艇生命力指标值及对应的损伤等级,是进行生命力评估的关键一步.技术设计阶段,舰艇生命力评估对象较多,评估对象之间的功能逻辑关系现复杂的网络状,因此以往方案设计阶段使用的损伤树分析方法将不再适用.针对该问题,首先分析了技术设计阶段生命力分析模型的构成,它包含3类分析模型；然后,使用图模型和宽度优先搜索算法构建了第1类分析模型；使用功能树模型构建了第2类分析模型；使用组合合成原则描述了第3类分析模型；最后,通过案例说明了上述分析方法的实用性.该分析方法具有较强的通用性,标准化程度高,为生命力评估系统的模块化开发奠定了理论基础.%Ship survivability analysis is calculating survivability index value and judge the damage level according to hull and equipment damage condition.Ship survivability analysis is a pivotal step in survivability assessment.In detailed design stage,the amount of assessment object is big and relation of assessment object is complex and netlike.So the damage tree analysis method which is used in preliminary design stage is not fit for detailed design stage.Aiming at this problem,the composing of analysis model which consists of three kind analysis model in detailed design stage is analyzed.And then,the graph model and width first search arithmetic are used to found the first kind analysis model.The function tree is used to found the second kind analysis model.The combined synthesis principle is used to describe the third kind analysis model.At last,the case is given to show the practicability of the analysis models founded above.The universal level and standard level of analysis method given in this paper is high and it is the theory basic of exploring modules of survivability assessment system.
