Failure analysis of the rubber-textile conveyor belts using classification models

Abstract

In real operations, the requirements on conveyor belts are very high and are constantly increasing. They mainly regard high wear resistance and resistance to the effects of the transported material, long service life, high longitudinal strength, low weight, etc.The main purpose of the present paper is the classification of the damage to rubber-textile conveyor belts that occurs due to the impact of the transported material (at the impact of the material onto a conveyor belt at the chute). The experimental research was focused on the three types of conveyor belts of various internal structures, on the impact height, and the type of the material falling onto a conveyor belt and effects thereof on the incurred damage. The damage classification was carried out using two different models. The models were created using the classification tree and the multiple regression analysis. The models were created using the training set of 48 conveyor belt samples. The accuracy and predictive ability of the models were verified using the testing set of 16 conveyor belt samples.
