直升机甲板连接件强度校核及疲劳分析

Strength checking and fatigue analysis of helicopter deck connection

船舶和海洋平台所处的海洋环境十分复杂,直升机甲板结构的可靠性引起了越来越多研究人员的重视。为了安全起见,直升机甲板除了整体结构需要满足规范要求外,局部结构也需深入分析研究。甲板连接件作为连接甲板和支撑框架的主要构件,其结构的可靠性直接影响着直升机平台的安全。因此,针对这一问题,文章分析了连接件结构强度和疲劳寿命。

The marine environment for the ship and offshore platform is very complex, and the reliability of the helicopter deck structure has attacted more and more researchers＇attention. In addition to the overall structural strength of the deck, it is necessary to study the local structure in detail. The connection is an integral part of the helicopter deck, and the reliability of the connection directly affects the safety of the structure. Therefore, in view of this problem, this paper analyzes the structural strength and fatigue life of the connection.
