【摘要】：移动救生补给站作为一种新型避险设备越来越受到重视,作为救生舱的替代产品,补给站相关标准还未出台;参照救生舱计算标准,采用安标中心指定的软件模拟井下瓦斯煤尘爆炸;采用间接耦合的方法进行计算,提取爆炸在巷道中产生的流场压力荷载,将该压力荷载作为救生补给站动力分析的荷载条件,对救生补给站在瓦斯爆炸下站体各机构的动力响应进行分析研究;通过分析研究各部件的受力及位移情况,找到补给站在爆炸下的薄弱构件,并对其进行研究改进,同时对气密性进行验证分析。
[Abstract]:As a new type of risk-averse equipment, mobile life-saving supply station has been paid more and more attention to. As a substitute product of lifebuoy, the relevant standard of resupply station has not been issued. According to the calculation standard of lifebuoy, the software designated by the safety standard center is used to simulate the underground gas and coal dust explosion. The indirect coupling method is used to calculate and extract the pressure load of the flow field generated by explosion in the tunnel. The pressure load is regarded as the load condition of the dynamic analysis of the rescue station. The dynamic response of each mechanism of the rescue station under the gas explosion is analyzed and studied. By analyzing and studying the stress and displacement of the components, the weak components of the supply station under the explosion are found and improved, and the air tightness is verified and analyzed at the same time.
