In view of the long-distance and high-power belt conveyor, the problem of huge impact on the belt conveyor in the acceleration and deceleration stage was analyzed. In order to improve the stability of belt conveyor operation and the accuracy of speed regulation, ensure its smooth movement process, reduce its impact and vibration, the characteristics of the existing acceleration and deceleration control were expounded, the root causes of the impact in the operation of large belt conveyor were analyzed, combined with its use process, the method and practice of implementing the motor speed S-shaped curve under the acceleration and deceleration conditions were discussed from the theoretical and practical aspects strategy. The practical application results show that using the S-shaped curve control constructed by double end drive, can obtain smooth speed, ensure the stable operation of the equipment, and meet the production needs.
