Abstract: The dynamic simulation model for belt of long distance belt conveyor was carried out based on the AMESIM software. The dynamic simulation of six kilo meters long distance belt conveyor was performed under the conditions of full loading, sine acceleration and different starting time. The change law of tension between the input point of the head of driving drum and the output point of the tail of belt was achieved under four kinds of starting time for long distance belt conveyor. The simu lating results showed that the tension decease considerably when starting time were increased. Meanwhile, a non- linear change law was obtained between the belt dyn amic features and increasing starting time.
