A pressure-resistant vessel is the core equipment of deep-diving equipment, which needs to have good pressure-resistant performance. In this paper, due to the problem that it is difficult to monitor the pressure-resistant vessel in the real diving process, we design a lightweight carbon fibre pressure-resistant vessel, construct a finite element model of the pressure-resistant vessel in deep diving, and carry out simulation and analysis, so as to provide a simulation test method for the real diving work. Specifically, the pressure-resistant vessel is subjected to finite element analysis at typical depths, and the floating process of the pressure-resistant vessel under different working conditions is simulated by using Computational Fluid Dynamics (CFD) simulation and orthogonal tests. Comparison of the CFD simulation results with the orthogonal test results proves that the selected pressure-resistant vessel can meet the working requirements under different working conditions.
