1. Calculate the peak value of conveying driving tension and its occurrence conditions during the operation of the conveyor. The peak value of the conveying driving tension is usually several times or even more than ten times of its normal operating tension, and the tension value calculated according to the previous static design method is much smaller than the actual value, so the safety factor can only be increased to ensure the safe operation of the conveyor. In the absence of reliable analysis tools, the safety factor determined by empirical methods is often too large, which will inevitably lead to rising costs and waste of investment.
2. The vibration characteristics of the conveyor belt in operation are analyzed. Vibration is the main reason that leads to the increase of conveyor driven tension, and it is also the culprit that causes the belt breaking accident. To find out its rules is of great significance to effectively control the conveyor driven tension.
3. The influence of boundary conditions on the vibration of conveyor belt is studied. The boundary conditions of conveyor belt refer to all internal and external conditions that affect the dynamic characteristics of conveyor belt, such as driving device, tensioning device, idler, load, etc. The influence of the change of these boundary conditions on the vibration is analyzed and studied, and the optimal form of the boundary conditions for optimizing the vibration characteristics of the conveyor belt is found; The comprehensive index of performance and economy is optimal.
