火灾环境下舰载弹药的安全性仿真分析
|
摘要
弹药的安全性一直是各国军事科技所关注的重点问题。火灾是舰上弹药贮存环境的主要安全威胁因素之一,论文以Mk-82舰载航空炸弹为研究对象,利用FDS(Fire Detection System)软件对舰上弹药舱室发生火灾的整个过程进行仿真分析,根据FDS仿真结果利用ANSYS软件对Mk-82在火灾环境激励下的温度场进行仿真,进一步对航空炸弹在火灾环境下的安全性进行分析。结果表明航空炸弹在火灾环境持续激励下,经70s后便可发生燃烧或爆炸,对全舰安全性造成巨大威胁。
The safety of ammunition has always been the focus of national military science and technology issues. And fire is one of the major safety threats to the ship's ammunition storage environment. In this paper,Mk-82 shipborne aviation bomb has been taken as the study object,simulated the whole process of fire by using the FDS(Fire Detection System)software. According to the simulation results of FDS,ANSYS software is used to simulate the temperature field of Mk-82 carrier-based aviation bomb under fire environment,and the safety of aviationbomb in fire environment is analyzed. The result shows that the aviation bomb under the fire environmentcan occurs the combustion or explosionafter 70 s constant cook-off,and it is a huge threat to the ship security.
