摘要
为探讨如何提高大型集体逃生舱的上浮安全性并优化大型集体逃生舱设计方案,对3种典型顶部设计(胶囊体、圆柱体、菱形体)的逃生舱模型,运用Fluent软件对其上浮状态进行了仿真模拟,计算得出各方案逃生舱上浮过程中的最大速度,比较了不同顶部设计方案的优缺点.结果表明,针对大型集体逃生舱,3种典型顶部设计不能达到安全上浮标准,还需结合其他减速手段.
In order to discuss how to improve the safety of large-sign escape capsule and optimize the design scheme of large-sign escape capsule, the escape capsules model with different top design was proposed in this paper, and the Fluent software was used to simulate the floating state of each design, and the maximum floating velocity of escape capsule with different top design of the submarine was calculated, the advantages and disadvantages of different top design schemes were analyzed and compared. The results showed that the designs proposed can not reach the standard of safe ascent, and it should be combined with other methods.
