This paper provides a belt conveyor's viscoelastic oscillatory equation, its displacement properties and calculation method of dynamic tension. It studies dynamic tension properties of the belt when the rectangular, sine and parabola acceleration are adopted, and gives a design method of limiting belt conveyor's viscoelastic vibration. The optimal soft starting and soft stopping control curves are recommended. An example of the slope conveyor in the Sha Qu Mine is presented for the calculation and comparision with numerical calculation results from American CDI (Conveyor Dynamics, Inc.); the two calculation results are very close. The method the paper provides can be applied to theoretical study and engineering design.
