圆碟形水下滑翔机是一种新型的水下滑翔机，耐压壳体则是滑翔机的重要组件。本文主要研究在不同水深下机身直径、机身高度与机身表面饱和度对耐压壳体表面变形与压力分布情况的影响。通过有限元分析表明在100～300 m水深范围内应减小机身直径，从而降低机身的最大变形量和最大应力。随着机身高度的增加，最大变形量和最大应力的变化规律是先减后增，且随着工作水深的增加，这种趋势越发明显。对于不同机身表面饱和度的圆碟型水下滑翔机，其外壳的最大变形和最大应力分布规律并不统一，机身饱和度较低的圆碟形滑翔机的综合性能较优。本文分析结果可为圆碟形滑翔机在不同深度下的外形设计提供参考。
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 maximum 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 performance of circular disc gliders with lower fuselage saturation is superior. The results of this paper can provide a technical reference for the shape design of DSUGs at different depths.
