Abstract

Detailed vibration measurements were undertaken at eight block type machine foundations with different supporting soil conditions. These extensive measurements were supplemented by theoretical vibration calculations using principally Barkan's method but, at times, using methods of Reissner, Pauw, Richart and Ford and Haddow. The results of prototype experiments and theoretical studies on various compressor foundations described above as also on similar foundations in the country justify broadly the validity of various theories, particularly Barkan’s method, though these are based on somewhat different concepts. Design criteria for foundations are generally described in terms of limiting values of amplitudes of displacement at the operating conditions. In general, the permissible amplitude of vibration decreases as the frequency increases. Thus, the allowable vibration amplitude has to be considered along with the operating frequency of machine.

Vibration Studies of Block Type Machine Foundations

Detailed vibration measurements were undertaken at eight block type machine foundations with different supporting soil conditions. These extensive measurements were supplemented by theoretical vibration calculations using principally Barkan's method but, at times, using methods of Reissner, Pauw, Richart and Ford and Haddow. The results of prototype experiments and theoretical studies on various compressor foundations described above as also on similar foundations in the country justify broadly the validity of various theories, particularly Barkan’s method, though these are based on somewhat different concepts. Design criteria for foundations are generally described in terms of limiting values of amplitudes of displacement at the operating conditions. In general, the permissible amplitude of vibration decreases as the frequency increases. Thus, the allowable vibration amplitude has to be considered along with the operating frequency of machine.
