Abstract
Manned submersible is an important equipment for marine resources exploration and development, and its structural framework is the basis to ensure the safety of divers. Based on the submergence data and maintenance records of the Jiaolong manned submersible, the operation process of the manned submersible is studied, and the influence of the operation process on the structure frame is analyzed from the aspects of ocean environment factors, the submersion time and the acceleration of the submersible in the operation process. The research shows that the wind wave load, seabed environmental pressure and seabed collision will all bring threats to the structure of manned submersible, and the wind wave load has the greatest impact on the structure safety of the submersible.
