Object of research: Rubber seal of the hatch of the underwater vehicle. The purpose of the study: Calculation of the seal of the MVP cover. The seals are arranged in two rows. Maximum pressure p = 3.2 MPa. The operating temperature is from T = -40℃ to T=+40℃ in air and from T= -2℃ to T = +30℃ in water. The maximum clearance is up to 3 mm. M. the axial linear load when closing the lid in air (at T = -40 ℃) F = 5 kN / m, when closing the lid in water (at T = -2 ℃) F = 2.5 kN /m. Results of the work: 1. A finite element model of the sealing unit is constructed, a stress-strain state is obtained for each stage of loading and for each variant of external conditions. 2. Strength was evaluated for all temperature and gap options. The constructed models are suitable for a given criterion of rigidity and tightness is not violated. 3. At a pressure of p = 3.6 MPa, the highest maximum stresses for the main rubber ï³i = 2.82 at a temperature of -40℃ in the version with a gap, for hard rubber ï³i = 7.81 v at a temperature of 0℃ in the version with a gap. 4. The seal with the gap-free option experiences less loads than in the gap-free version, therefore, the gap-free option is preferred for operation. 5. At all temperatures and gaps, the seal works without damage and ensures the tightness of the underwater vehicle.
