Belt Conveyor Dynamic Characteristics and Influential Factors

Maximum dynamic tension in the conveyor belt occurs at the drive drum and gradually reduces away from the drum. Dynamic tension fluctuation amplitude decreases with increasing, which is consistent with the time response characteristics and indicates that viscous damping increases the belt dissipation capacity. As increases, energy dissipation increases and stability improves.
