Problems concerned experimental detemination of dynamic properties of complex structures supporting the bearings of rotary machinery have been presented in the paper. Experiences, aqiured during practical application of known methodology of harmonic excitation on the area of determination of the properties of the huge test bench for investigations of the rotor dynamics and its slide bearings, are discussed. Preliminary concept od application of this methodology and modifications stemming from the accumulated experiences has been indicated. Obtained results have been illustrated by the graphs of modules and phases of flexibility matrix also relevant dstributions of the coefficients of equivalent stiffness and damping coefficients.
