THE INFLUENCE OF INCRUSTATION AND CHUTE BLOCKAGE ON THE DYNAMIC BEHAVIOUR OF A BUCKET WHEEL EXCAVATOR SLEWING SUPERSTRUCTURE

Nebojša Bogdan Gnjatović, Srđan Momčilo Bošnjak, Ivan Ljubodrag Milenović
Exploitation of bucket wheel excavators (BWEs) is accompanied by an increase of mass due to transport and adherence of large amount of material. Technical regulations do not account for the dynamic behaviour of BWEs. Such problems are analysed as quasi-static. Procedure and results of investigation of the influence of masses of bucket wheel (BW) incrustation and soil in blocked BW chute on superstructure response are presented. Analysis of sensitivity of the dynamic characteristics and response to adherence of material was conducted. The method and results can be used in the design stages of new and in reconstructions of obsolete BWEs.
