| 摘 要： | 制作了一个含凸、凹型加肋锥-环-柱结合壳的连接结构焊接钢模,进行了静水外压试验,研究连接结构的应力分布.环壳块的嵌入有效地削减了锥-柱结合部的应力峰值.模型在大圆柱壳破坏,表明连接结构的强度高于所连接的基本结构(环肋圆柱壳)的强度.实验证明含凸、凹型加肋锥-环-柱结合壳是潜艇耐压艇体相邻的大、小圆柱壳间一种优越的连接结...

| 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 s... |
