Assessment methods of conveyor belts impact resistance to the dynamic action of a concentrated load

The methods of testing the conveyor belt’s puncture resistance in terms of assessing their suitability for the transport of sharp-edged rocks are presented. Methods of determining the critical impact energy of strokes are discussed together with a new method for determining the critical energy and the method of determining the average impact energy taking into account selected range of belt damages, which more reliably characterize their impact resistance. The algorithm and the method of estimating the critical impact energy based on measurements of energy absorbed by belt during rock mass strike is presented.
