Test Method for Surface and Underwater Condition of Deep-sea Special Pressure Structure

  • 摘要: 分离头盖是深海无人系统的特种耐压结构, 需兼顾水下长期耐压与水面快速分离功能。为研究深海特种耐压结构水面-水下复杂工况综合性能, 研制了分离头盖实尺度结构模型开展水压试验和分离试验研究。首先, 针对分离头盖水下服役时面临的长周期海水压力环境试验工况需求, 基于国内现有的常规深海环境模拟试验系统, 提出了一种通过带皮囊球的舱室装置来实现大深度海水-压力耦合环境模拟的试验方法。再者, 针对分离头盖出水后的水面状态(空气中)快速分离试验工况需求, 建立了一套安全可靠的斜法兰连接结构模型快速分离试验系统。分离头盖实尺度模型试验结果表明, 论文提出的特种耐压结构水面-水下复杂工况试验方法合理可行, 不仅可用于分离头盖的水压试验和分离试验研究, 也可为其他深海装备类似耐压结构的相关设计与试验提供一定参考。
