摘　　要：船舶结构长期在波浪等多种载荷的作用下会发生结构件的疲劳失效,为了确保船舶运行的安全性,提前对船舶结构的应力故障进行监测和识别。本文设计一种基于应力测量和响应技术的船舶结构可靠性监测系统,介绍船舶结构应力数据采集原理、光纤光栅传感器工作原理、结构可靠性监测系统的主要构成等,并结合软件程序进行波浪载荷作用下的船体甲板结构应力数据测量仿真。本文研究对于改善船舶航行安全性,提升船舶监测水平有一定意义。The fatigue failure of ship structure will occur under the action of various loads such as waves for a long time. In order to ensure the safety of ship operation and monitor and identify the stress failure of ship structure in advance,this paper designs a ship structure reliability monitoring system based on stress measurement and response technology, and introduces the principle of ship structure stress data collection, the working principle of fiber grating sensor The main structure of the structural reliability monitoring system, and the stress data measurement simulation of the ship deck structure under the wave load is carried out by combining the software program. This research has important significance for improving the navigation safety of ships and improving the ship monitoring level.
