Abstract：[Objective]To address the longitudinal vibration of long-distance belt conveyors during starting,the dynamic equations of the belt conveyor were established based on the analysis of the viscoelastic properties of the conveyor belt.Taking a practical long-distance belt conveyor as an example,a dynamic simulation model was constructed using AMESim software to study the starting acceleration curve and loading time.[Methods]The effects of common starting curves on the dynamic tension of the conveyor belt were analyzed,and a new combined starting curve(sine+parabolic)was proposed.The curve was optimized by introducing a creep phase and adjusting the pre-starting speed.The tension variations under different loading times were then analyzed.[Results]The results show that the optimized sine and parabolic starting curve reduces the maximum tension of the conveyor belt by 5.8%compared with the commonly used sine acceleration curve.Furthermore,loading materials after stable op-eration effectively reduces the tension impact and extends the service life of the conveyor belt.
