The influence of constructive parameters on response of bucket wheel excavator superstructure is investigated by using a four degrees-of-freedom discrete dynamic model. Four representative geometric configurations of the superstructure are examined. The maximum displacements and accelerations are observed when the bucket wheel boom is in its lowest position. Further analysis on this configuration is performed to determine the effects of the structural elements stiffness and the bucket wheel weight on the system response. A set of the magnitudes of the parameters that may cause resonance are also determined.
