摘要/Abstract

摘要： 环形耐压壳具有较好的抗压能力和水动力特性,是深海空间站的一种优选结构。既有研究主要对圆截面环形耐压壳以及加肋圆截面环壳进行了屈曲分析,对椭圆截面环壳的研究缺乏试验支撑。为进一步探究椭圆截面环形耐压壳的屈曲特性。通过基于弧长法的非线性数值计算,分析椭圆截面长、短轴比值对环形耐压壳屈曲载荷的影响规律,优选出一组椭圆参数。采用快速成型技术制作两个树脂材料椭圆截面环形耐压壳,以及两个等体积、等质量的树脂材料圆截面环形耐压壳,进行几何测量、静水外压和数值计算。结果表明,长、短轴比值为1.27的椭圆截面环形耐压壳具有良好的抗压性能,其屈曲载荷是等效圆截面环形耐压壳的1.718倍,该研究可为深海空间站载人舱的创新设计提供参考。

Abstract: The toroidal pressure hull is a kind of optimal structure for the deep-sea space station because of its good compressive strength and hydrodynamic characteristics. The buckling analysis on circular cross-section toroidal shells and ribbed circular cross-section toroidal shells are mainly conducted in existing studies, but experimental support on the study of elliptical cross-section toroidal shells is lacked. In order to further explore the buckling properties of the elliptical cross-section toroidal shells. Through the nonlinear numerical calculation based on the arc length method, the influence of the ratio of the long and short axis of the elliptical section on the buckling load of the toroidal pressure shell is analyzed, and a set of elliptic parameters is optimized. Two resin material elliptical section toroidal shells and two resin material circular cross-section toroidal shells of equal volume and equal mass are made by rapid prototyping technology for geometric measurement, hydrostatic external pressure test and numerical calculation. The results show that the elliptical cross-section pressure shell with the ratio of long and short axis of 1.27 has good compressive performance,and its buckling is 1.718 times that of the equivalent circular cross-section toroidal pressure hull. This study can provide a reference for the innovative design of the manned cabin of the underwater space station.

Key words: toroidal pressure hull, elliptical cross-section, circular cross-section, buckling load, deep sea space station
