Title:
DETERIORATION MEASUREMENT DEVICE AND DETERIORATION MEASUREMENT METHOD FOR ADHESION JUNCTION
Document Type and Number:
Japanese Patent JP2022142527
Kind Code:
A
Abstract:
To provide a deterioration measurement device for an adhesion junction, capable of measuring a deterioration state of an adhesive in the adhesion junction of a measurement object in which two adherends are bonded with the adhesive.SOLUTION: A deterioration measurement device for an adhesion junction for measuring a deterioration state of an adhesive in an adhesion junction of a measurement object in which two adherends are bonded with the adhesive, includes: supersonic wave transmission means that irradiates the adhesion junction with supersonic waves having three waves or more; supersonic wave reception means that measures a transmitted wave amplitude of the supersonic waves transmitted through the adhesion junction; and analysis means that calculates a Young's modulus of the adhesive in the adhesion junction from the transmitted wave amplitude measured by the supersonic wave reception means on the basis of a calibration curve indicating the relation between the Young's modulus of the adhesive and amplitude transmittance in the adhesion junction.SELECTED DRAWING: Figure 1
