Reappraisal of Pressure Distribution Induced by Ice-Structure Interaction Using High-Precision Pressure Measurement Film

摘要

'Spatial' pressure-area curves are required to determinedesign loads on a local structure, such as plates and frames in ice load condition. However, plotting a practical 'spatial' pressure-area curve is difficultdue to the sensitivity of frequency and resolution of data acquisition.In this study, spatial pressure-area curveplotting was attemptedusing high-precision pressure measurement film with stepped crushing method. Additionally, creation of a pressure distribution map at specific time steps was facilitatedby stacking different ranges of pressure measurement film.
