Life management system for casing of tire and life management method of tire casing

摘要

Problem to be solved: to provide a life control system for a casing of a tire which can easily predict a remaining life period of a casing and a casing life management method for a tire.Casing life management system 100A temperature sensor 3B for measuring the temperature of tire 2 andBased on the temperature information of the tire 2 measured in the first period of at least one more dayThe thermal hysteresis amount calculating section 39 calculates the thermal hysteresis quantity received by the tire 2 during the first period of timeBased on the thermal history of the first periodThe cumulative heat quantity estimate Part 40 which estimates the cumulative heat quantity that the tire 2 can receive in the second period set for one year isFrom the cumulative heat of the second period and the predetermined thresholdThe casing life prediction section 41 predicts the remaining life of the casing.Diagram
