Abstract: The design of compressive cabin which is used in the underwater vehicle requires that the design strength and stability can be improved to the maximum, and the weight can be reduced as much as possible to satisfy the requirements of the overall index. The Design Explorer Module in ANSYS Workbench was used for the fast optimization design of the compressive cabin, and a number of optimal candidate results were obtained at one time. The optimal design scheme was obtained by comparison and analysis. Then, contact analysis was carried out in the form of assembly to ensure that the structure would not fail under the condition of high pressure. Finally, the stability analysis of the cabin structure was carried out to ensure that the structure could not cause instability failure in a large depth environment. The result of this study provides the reference for rapid optimization design, strength and stability checking of the underwater vehicle's compressive cabin.
