Experimental analysis and prediction for the bonding strength of steel cord of conveyor belt under the temperature influence

To research the effect of temperature on interfacial bonding strength steel cord rubber conveyor belt, an electronic universal material testing machine and a control box were used as test equipment. The withdrawal force skeleton belt was tested in range −30 °C to +40 °C. Concurrently, morphology between at different temperatures observed by using ultra deep field electron microscope. Finally, prediction models established. results show that variation trend with displacement is same temperatures. With increase temperature, matrix decreases gradually; second-order polynomial model can meet requirements temperatures, errors are controlled within 5%.
