摘要
Abstract
A joining structure steel model, composed of ring-stiffened, convex and concave cone-toroid-cylinder combination shell, was manufactured and tested under hydrostatic external pressure. The stress distribution of the joining structure model was measured and studied. The peak stress at the joining section between cone and cylinder was effectively reduced due to the insertion of a toroid segment. Collapse of the model occurred at cylindrical shell with large diameter, which demonstrated that the strength of joining structure was higher than the strength of the structures being joined. Model test results verified that the ring-stiffened convex and concave cone-toroid-cylinder combination shell is an excellent joining structure form between cylinders with different diameters in submarine pressure hull. By analyzing the collapse mode of the model-yielding of cylindrical shell between ring stiffeners, the authors point out the importance of studying the problem of the plastic limit load of ring-stiffened cylindrical shell in modern submarine structural design.关键词
