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