Monitor Technology Research on Hull Structure Condition

Abstract

On the basis of analyzing the necessity and significance of the condition monitoring of hull structure, aiming at the two key technical problems of selecting monitoring points and ship sensing and communication technology, the effective solutions are proposed. For the first problem, the response functions of structure stress under external loads were obtained through the method of the whole ship structural finite element analysis, the monitoring points were selected in two methods which are finding the monitoring points on the area of high-stress and considering the information of sea states. As for the second problem, supplies a complete framework for hull monitoring and assessment system based on fiber Bragg grating technology, analyzes the system’s composition and the function of each part briefly.
