Models of Transverse Vibration in Conveyor Belt—Investigation and Analysis

The transverse vibration frequency of conveyor belts is an important parameter describing the dynamic characteristics a belt conveyor. This most often identified from theoretical relationships, which are derived on basis assumption that stationary elastic string. Belt vibrations have number analogies to other tension member systems, such as, for example, power transmission belts. Some research findings suggest in case limited length section, more accurate description its can be obtained with beam model rather than string model. Experimental has so far mostly revolved around measurements article presents results performed moving and various operating parameters conveyor, as well several configurations distance between idler supports. analysis was conducted steel-cord belt. Belts this type commonly used majority mines industrial plants. measurement were compared tension. Both models allowed speed, whose influence demonstrated both calculations experimental tests negligible. On hand, tensile force observed significant impact frequency. Depending spacing, approximate those or For spacing smaller 1.6 m, shows properties beam, while greater behaviour better represented through A is, therefore, applicable analyses upper strand belt, useful lower strand.
