The invention belongs to the field of application of pressure-resistant shells of underwater vehicles, and particularly relates to an annular rib structure of a variable-cross-section equal-rigidity pressure-resistant shell. Comprising a plurality of arc-shaped connecting sections arranged in an annular array and a plurality of supporting sections arranged between the arc-shaped connecting sections. The section of the arc-shaped connecting section is I-shaped, and the arc-shaped connecting section comprises an arc-shaped panel, a lap plate and a web plate located between the panel and the lap plate, wherein the panel and the lap plate are coaxially arranged; the inner edge of the web plate is connected with the surface of the outer side wall face of the panel, and the thickness of the supporting section is not smaller than that of the arc-shaped connecting section. According to the variable-cross-section equal-rigidity pressure-resistant shell annular rib structure, a variable-cross-section rib and equipment rack conformal design is adopted, and the variable-cross-section equal-rigidity pressure-resistant shell annular rib structure is used for a pressure-resistant shell of a marine aircraft, an aircraft fuselage shell and other large-scale equipment needing to be borne and can bear single loads such as axial pressure, axial pressure and the like. The combined action of multidirectional loads such as hydrostatic pressure can also be borne, and the space utilization rate and the bearing capacity of the structure are both improved through the ribs.
本发明属于潜航器耐压壳体应用领域,尤其涉及一种变截面等刚度耐压壳体环形肋骨结构。包括若干呈环形阵列设置的弧形连接段以及设于弧形连接段之间的若干支撑段;所述弧形连接段截面呈工字型,包括呈弧形且同轴设置的面板和搭接板以及位于面板和搭接板之间的腹板;所述腹板内缘与面板外侧壁面表面连接,所述支撑段厚度不低于弧形连接段的厚度。本发明的变截面等刚度耐压壳体环形肋骨结构采用变截面肋骨与设备机架共型设计,用于海洋航行器的耐压壳体、航空器机身壳体以及其他需要承载的大型设备中,其可以承受单一载荷如轴压,也可以承受多方向载荷联合作用如静水压力,通过此肋骨实现结构的空间利用率和承载能力的双重提高。
