Title:
ホースの残存寿命予測方法及びホースの残存寿命予測システム
Document Type and Number:
Japanese Patent JP7396832
Kind Code:
B2
Abstract:
A method and system for easily predicting a remaining lifetime of a hose are provided. A hose remaining lifetime prediction method and a hose remaining lifetime prediction system, for predicting a remaining lifetime of a hose 1 in use, include obtaining in advance, for a hose of the same type, relationship between use time of an inner tubular rubber layer 11 at a reference temperature and a physical property value of rubber forming the inner tubular rubber layer 11, generating a thermal degradation model for the inner tubular rubber layer 11, calculating, for the hose 1 in use, reference temperature use time being use time of the inner tubular rubber layer 11 at the reference temperature until a time of the prediction, and predicting the remaining lifetime of the hose 1 in use, based on comparison between the reference temperature use time and the thermal degradation model.
