Sažetak
The present paper deals with the problem of improving dynamic characteristics for a sub-structure of bucket wheel excavator. The procedure is concerned with the analysis of the distribution of potential and kinetic energy in elements of the structure, which gives prediction for which elements reanalysis is needed. Reanalysis technique can be done for the structure using finite element methods. Information like material, geometry and boundary conditions should be prepared before making FE model. The main aim of dynamic modification is to increase natural frequencies and to increase the difference between them.
