船舶结构分布式测量系统及其模型

基于船舶挠性结构变形测量的现状、捷联惯导系统的应用现状和目前光纤布拉格传感器可复合使用、波长编码的独特优点,本文提出采用捷联惯导系统与分布式光纤布拉格光栅组成对船舶结构进行变形测量和健康监测的设计方案,分析了可行性,并建立了由捷联惯性系统和光纤布拉格传感器组成的光电多传感器初步测量模型.

Distributed Measurement System and Its Model for Ship Structure

Based on the state-of-art of deformation measurement of ship structure, the application status of strap-down inertial system and the unique advantages of compound application and wavelength coding of Fiber Bragg Grating(FBG) sensor, a new method, which employs distributed FBG and strap-down inertial system to constitute a distributed measurement system, for deformation measurement and healthy diagnosis of ship structure is proposed. Its feasibility is analyzed. A preliminary measurement model composed of strap-down inertial system and FBG and including optical and electronic sensors is set up.
