Abstract
Belt is an important and expensive part of the conveyor belt system. At the early seconds of the starting process, maximum belt stretch is found which causes sudden failures or enormous starting belt stress. These dynamic stresses are difficult to measure and their presence could therefore go undetected. The transient stretch in the belt is investigated for the actual belt conveyor during full load starting condition. Belt conveyor system is considered as the series of vibrating mass and this unit is a viscoelastic segment; equation of motion is developed through the approach of Lagrange to study this process. Simulation technique is used to observe transient dynamic quantities. Dynamic belt stretch is studied in terms of dislocation within the conjugative units of endless belt. Result indicates that the maximum dynamic stretch value is 1.7 percent of the total length of the belt which comprises standard values specified for system. Dynamic stretch analysis would reveal the actual behavior of dynamic belt stresses in the conveyor belt.
