Field Measurement of Coupled Vibration Foundation Parameters for Three-degree-of-freedom System

In this paper has been presented the method for determining the parameters kx, cx, ky, cy, kφ,, cφ of a vibration foundation couplsd in rocking, horizontal and vertical modes with amplitude measurements on several points. The proposed method has no special requirements for the damping factor of the system. It is possible to find the frequency-dependent parameters of the system using the measurements obtained from various frequencies.
