description: The given work is devoted to the studying of the strength of the underwater vehicle when it impacts with the bottom. The research set the following goals: 1. Studying of models of materials for modeling the behavior of polymethylmethacrylate; 2. Preliminary static structural analysis; 3. Investigation of the ships structure for strength in case of impact with the bottom, using selected models of the material; 4. Analysis of the results obtained, conclusions about the operability of the underwater vehicle The collection and analysis of scientific and technical literature about the object of research was carried out. Material models for the task have been identified. A preliminary static calculation was carried out in the ANSYS software package to assess the strength. Transient analyses were made showing differences in the behavior of different material models. The final calculation of the impact of the underwater vehicle with the bottom was performed in the LS-DYNA software package. As a result, stress and strain fields were obtained at the moment of impact and after it. Figures of stresses and displacements in various zones of the structure are considered. Based on the results obtained, a conclusion was made about the operability of the structure in an emergency.
