一、前言造船技术不断发展,焊接工艺广泛应用,并日趋完善,出现了越来越多的全焊接船舶。另一方面,铆接因其具有独特作用,至今仍在船舶的部分结构中采用。为了防止船体裂缝的产生和延展,除需设计正确合理的结构型式和采用优质钢材外,还考虑在应力集中的部位采用铆接结构,使构件形成铆钉结构所特有的断续连接。由于铆接接头的柔性,促使应力重新分布,因而在相当大的程度内减轻了结构对应力集中的敏感性,起到
First, the foreword The continuous development of shipbuilding technology, welding technology is widely used, and maturing, there has been more and more all-welded vessels. On the other hand, riveting has so far been employed in some parts of the ship due to its unique role. In order to prevent the occurrence and extension of the hull cracks, in addition to the need to design a correct and reasonable structure type and the use of high-quality steel, but also consider the stress concentration of the site using riveting structure, the formation of rivets to form a unique intermittent connection. As a result of the flexibility of the riveted joints, the stress redistribution is facilitated, thus reducing the sensitivity of the structure to stress concentration to a considerable extent,
