Application of the method of reducing rotating masses in mining transport systems

Popis výsledku v původním jazyce

In recent years, belt conveyors have been among the most widespread means of transport in the mining industry and because of this they are developing very quickly in terms of design. The key element of the belt conveyor is its drive unit. Random vibrations of the belt conveyor drive pose a great risk of downtime. The solution is to minimize dangerous vibrations occurring in the belt conveyor drive by predicting their occurrence using dynamic models. The article presents a complete dynamic model that describes the real mechanical system and its verification by the method of reducing the number of degrees of freedom of replacement dynamic torsion systems. When creating models, the method of partial frequencies is applied to a six-mass mechanical system. Subsequently, the calculation of the reduced new system is compared with the calculation of the original system. At the same time, a simulation calculation approach in the MATLAB program is also applied. The calculations aim to determine the specific angular frequencies and mode shapes for each degree of reduction and system type. The calculation model using the Holzer tabular method is verified by calculation in the MATLAB simulation program. Both approaches provide good technical accuracy with a tolerance of up to 5 %.
