Part of the International Centre for Mechanical Sciences book series (CISM, volume 273)


A method for calculating the global three-dimensional dynamic response of machine foundations interacting with subsoil and excited by rotor unbalances is presented. Fig. 1 shows a low-tuned steel foundation with a concrete raft. The light upper steel plate on flexible columns has the advantage to minimize the amplitudes of shaft whirling relative to the bearings.
