摘要
为解决现有柱形贮箱使用的各类推进剂贮存管理装置的不足,打破金属隔膜式装置的传统结构形式限制,提出了新型柱形金属隔膜。介绍了其结构组成和工作原理,根据其工作特点对隔膜型面开展参数设计,再采用有限元模拟方法对隔膜壁厚分布进行仿真优化,并生产隔膜试验件进行排放试验验证。结果表明:新型柱形隔膜膨胀变形平顺规律未失效,排放效率和排放压差均可接受,为其在柱形贮箱中的工程化应用提供了技术支持和数据支撑。
To solve the insufficiency problem of various propellant storage and management devices used in the existing cylindrical tanks,and to overcome the limitations of the traditional structure of metal diaphragm devices,a new cylindrical metal diaphragm was proposed.First,the structure and working principle were introduced.Then the diaphragm surface was designed according to the working characteristics and the thickness distribution of diaphragm wall was optimized by finite element simulation.Moreover,the diaphragm specimen was produced and the diaphragm expulsion experiment was conducted.The results showed that the expansion deformation of the cylindrical diaphragm was smooth and regular,and the expulsion efficiency and pressure were acceptable.The results may provide technical and data support for its engineering application in cylindrical tank.
