Optimized design of pressure hull of disk-shaped underwater glider
The disk-shaped underwater glider(DSUG)is a new type of underwater glider,and the pressure hull is an important component of the glider.In this paper,the effects of shell diameter,shell height and shell surface saturation on the surface deformation and pressure distribution of the pressure hull are mainly studied.Analysis results show that diameter of the shell should be reduced in the water depth range of 100m～300m so as to reduce the maximum deformation and maxim-um stress.With the increase of the height of the shell,the maximum deformation and maximum stress decrease first and then increase,and this trend becomes more obvious with the increase of the working water depth.The maximum deformation and stress distribution of the shell of DSUG with different shell surface saturation are not uniform.The comprehensive perform-ance of circular disc gliders with lower fuselage saturation is superior.The results of this paper can provide a technical refer-ence for the shape design of DSUGs at different depths.
