摘要
根据舰船实际和火灾理论,建立了舰船舱室火灾危险性的动静二类4个指标:失火危险性指标、舱室相关度指标、设备使用状态指标和人员状态指标,对舰船各种舱室的火灾危险性进行量化。笔者先给出规范中9类舱室的各指标值,应用笔者所开发的神经网络模型,建立舱室火灾危险性指标值与舱室分隔等级的关系模型,求出舱室防火分隔等级值,降低了对设计者经验的要求。运用开发的模型对某大型舱室进行防火设计,获得的结果与其他方法的结果基本一致,可供舰船防火设计时参考。
Referring to the status of naval vessels and fire theory, four indexes of dynamic and static categories for the fire risks in the cabin of naval vessel are established, i.e. index of fire risk, index of cabin correlation, index of equipment status and index of crew members, with which the fire risks in cabins of naval vessels are quantified. Values of various indexes of 9 categories of cabins are given. The neural network model developed is applied to establish the correlation model of index value of fire risk in the cabin with the isolation rank of the cabin, from which the isolation rank value of the cabin could be obtained with less demand of designer's experience. This model is used in the fire-fighting design of a big cabin; the result obtained is in compliance with that of other method. This method might be used as a reference in fire-fighting design for naval vessels.
