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 hosein use, include obtaining in advance, for a hose of the same type, relationship between use time of an inner tubular rubber layerat a reference temperature and a physical property value of rubber forming the inner tubular rubber layer, generating a thermal degradation model for the inner tubular rubber layer, calculating, for the hosein use, reference temperature use time being use time of the inner tubular rubber layerat the reference temperature until a time of the prediction, and predicting the remaining lifetime of the hosein use, based on comparison between the reference temperature use time and the thermal degradation model.
