Analysis of new starting curve and dynamic characteristics of long-distance belt conveyors
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
2
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
2
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 operation effectively reduces the tension impact and extends the service life of the conveyor belt.
