摘　　要：将火灾区域模拟方法运用到舰船舱室火灾分析中,建立了全船各舱室的区域模拟模型,进行了模拟计算;根据火灾形成和蔓延的机制,确定了火灾蔓延判据,进行了全船火灾危险等级划分;在舱室区域模拟的基础上,应用模拟试验的方法,针对不同武器攻击情况,根据火灾蔓延判据和危险等级划分,编制了全船综合性评估程序,对全船火灾危险性进行评估.This paper proposes some modifications all-owing extending zone models to ship design applications, a pressure solution procedure for multiple compartments and an approach to heat conduction de scription in complex geometries. Zone fire model is applied in naval ship fire analysis, different compartments model for zone model calculation are set up, and calculation results are presented. According to the mechanism of fire engendering and spreading, the criterions of fire spreading and fire hazard rate are built. On the basis of zone simulation of single compartment, a fire modeling in multiple ship compartments are proposed, which can be used to assess fire hazard. A program is compiled to prove this method, it can be used to assess ship fire hazard at different situation of weapon attack.
