| Abstract: | Applying thin-walled structure engineering design method for torpedo and mine,the curve tail shell specimen was designed and fabricated with the material ZM5-T6,carrying out specimen performance experiment in different external hydraulic loads distributed uniformly.In the process of hydraulic loads increased to 1 .60 MPa,the specimen connection and seal in two ports stabilizes,equivalent stresses of specimen in all measuring points increase in linear relation,maximum stress and deformation of the shell complying with the design requirement.Magnesium alloy ZM5 is used as lightweight material of the pressure-resistant tail shell,the casting quality and loads bearing performance can be ensured from design and technology. |
