ANALYSIS OF EXPERIMENTAL RESULTS OF UNDERWATER SHIP STRUCTURAL MODEL AND FULL-SCALE

Underwater pressure hull consists of framed cylindrical, conical and spherical shells with various diameters. The purpose of this paper is to describe several research activities concerning the model and full scale tests of underwater ship structures conducted at China Ship Scientific Research Center (CSSRC) in recent years: Modelling (theory and method) of underwater structures. Testing facilities and measuring system of underwater structure model. Measuring technique of prototype on initial sea trials and also in yards. Comparison between test results and theoretical predictions. Emphasis is placed on selection of model scale, the requirement of model fabrication, the modelling methods and its facilities, pressure tanks, the measuring technique of prototype on initial sea trials, such as waterproof technique for strain gauges during the deep diving test, the watertight device which bring the measuring electrical leads from the outside to the inside of the hull without destroying the watertight integrity of the pressure hull. The paper describes also the multipoint automatic strain recorder and its data processing system during the deep diving test in real sea, and the comparison between test results and theoretical predictions as correlations between scale model results, full scale measurements and theory.
