Abstract
A method of recognizing a conveyor belt wear condition is provided. Relationships between an apparent compressive stress in a wear resistance test and surface roughness of a sample and between the surface roughness and amount of wear per unit frictional energy of the sample are acquired. A wear condition of an upper cover rubber is recognized based on an apparent compressive stress generated on the upper cover rubber at a use site, and a database is created based on the relationships. Alternatively, relationships between an average wear pitch calculated from the surface roughness and viscoelastic properties of the sample and between the average wear pitch and an actual amount of wear of the sample are acquired. A wear condition of the upper cover rubber is recognized based on the viscoelastic properties of the upper cover rubber of the use site and a database is created based on the relationships.
