| Abstract: |
| Objective To study mechanical properties of submarine launch canister protection cover under deepwater pressure and temperature load. Methods Model for mechanical and temperature load of protection cover was established. Finite-element method was used to analyze the stress, deformation, temperature distribution and thermal structure under those loads. Results Under deep water pressure, the deformation was 0.977 cm to 1.47 cm, the stress was 1.22 MPa ~ 7.91 MPa. Under temperature load, the deformation of the protection cover is 0.92~1.38 cm and the stress was 0.272 kPa ~ 1.26 MPa. Conclusion The maximum deformation of protection cover was on centre portion in two working conditions, so the structural strength of centre portion should be reinforced, otherwise it would be damaged. |
