Title:
STRESS DISTRIBUTION MEASUREMENT METHOD AND STRESS DISTRIBUTION MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/141294
Kind Code:
A1
Abstract:
This stress distribution measurement method for measuring a distribution of stress generated, in a structure having two support parts and a beam part between the support parts, due to movement of a movable body on the structure, comprises: a step (S102) of generating first image data by photographing the movable body by means of a first photographing unit or photographing, from the movable body, an identification display object attached on the structure; steps (S103, S106) of determining, on the basis of the first image data, a movement period during which the movable body moves between the support parts of the structure; a step (S105) of generating thermal image data (second image data) by photographing a surface of the beam part of the structure by means of a second photographing unit; a step (S108) of determining a temperature change amount on the basis of a second image data group, in the second image data, corresponding to the movement period; and a step (S109) of calculating a stress change amount on the basis of the temperature change amount and determining a stress distribution on the basis of the stress change amount.
