Originální abstrakt

In case of bucket wheel excavators (BWE) the digging forces are dominant sources of vibrations. The influence of digging forces on steel structures of upper part of BWE depends on position of terrace. Structural configuration of BWE is different while cutting terrace on the ground level or higher level. It causes changes of stiffness of steel structure and changes of natural frequencies of BWE. More over location of the resultant of digging forces changes too. Huge measurement of vibrations of the steel structure of upper part of BWE SchRs 1320 was made during operation. The paper deals with the influence of changes in locations of the bucket wheel boom to vibrations of the steel structure of upper part of BWE SchRs 1320.
