| 摘 要： | 为了提高CSR(BC)规范下散货船底部纵骨在防倾肘板连接处的疲劳寿命,采用有限元法比较几种不同切口形式在热点处的应力集中系数,确定其中有效的几种形式,使用共同规范的直接计算法予以证明,为便于使用,针对这些切口形式给出在CSR(BC)简化计算法中可以参照使用的系数。

| Abstract: | A serial of connection details are researched for rising fatigue life of bottom longitudinal connection at tripping brackets under CSR （ BC） rule.The comparing of the stress concentration factors between them is applied by FEM analysis . Some of cutting details are proved to be very effective for rising fatigue life .The corresponding geometric stress concentration fac-tors are provided for these cuttings based on CSR （ BC） fatigue simplified calculation method . |
