摘　　要：考虑到船舶在倾斜、运动,以及风的影响下,集装箱船组合吊臂托架的前桅受到克令吊对吊臂托架的载荷作用,其结构强度问题需要重点关注,以某集装箱船组合吊臂托架的D形前桅为例,采用有限元数值模拟的方法对该前桅进行直接计算分析,结果表明,通过合理的肘板设计可有效降低肘板趾端的峰值应力并满足规范要求。The foremast with crane supporting for container ship is subjected to the load of crane on the crane support because of the ship tilting,motion and wind and its structural strength is the focus of attention.The D-type foremast of a container ship was taken as an example,and the structural strength of the foremast with crane supporting of this ship was assessed by finite element method.The numerical results showed that structural stress concentration in the bracket toe has been reduced by adjusting the design of the bracket,so as to meet the rule requirement.
