Abstract

The stability of submarine pressure cylindrical shell is the main factor that restricts the diving of submarine for a long time, and it is also one of the important contents for designing and checking of submarine pressure structure. It is well known that a way to improve the stability of submarine pressure cylindrical shell is increasing the thickness or improve the ring stiffness, in fact, the increasing thickness is a kind of effective method to improve the stability of ring-stiffened cylindrical shell with long compartment, however, the improvement of overall stability for the cylindrical shell cannot achieve by increasing its ring stiffness, which can be regarded as the “Abnormal characteristics” appears in the structure. This paper mainly investigates the abnormal characteristics of the ring-stiffened cylindrical shell with a long compartment, which should be mastered by undergraduate students majoring in Naval Architecture and Ocean Engineering. The investigation results provide references for the reform of the course system of structural mechanics of underwater pressure shell.
