深海载人潜水器的坐底分析

文章以某深海载人潜水器为例,提出深海载人潜水器坐底的计算分析方法,利用该方法对该潜水器的坐底过程进行了计算分析,最后提出一些坐底建议.文中的研究内容主要包括(1)海底为岩石地貌条件下,采用理论分析与碰撞有限元分析相结合的方法,对潜水器在不同坐底接触姿态下的坐底安全进行分析,对潜水器坐底支架的结构强度进行校核;(2)海底为软沉积物地基状态下,提出了潜水器坐底计算方法分析、坐底过程控制方法,并进行了坐底安全分析.文中还根据计算分析结果对深潜器的坐底过程提出了安全控制技术指标要求和相关建议.

Landing research on deep-sea Human Occupied Vehicle

Up to now, no formal analysis methods on landing safety of HOVs were found in the public literature. In this paper, the landing process of an HOV is analyzed. Some calculation formulae are deducted. A practical HOV is used as an example to analyze the landing process. The main contents of this paper focus on: (1) Using theoretical and FE methods to analyze the strength safety for the HOV landing on rocky seabed. (2) Using theoretical methods to analyze the landing process,landing control measures for the HOV landing on soft sediment seabed. According to the calculation results, some operation requirements are proposed.
