Abstract

Machinery can affect engineering structures, as well as foundations supporting them and resting directly on the soil. Machines cause distinct dynamic forces depending on its manufacturing purposes, operating conditions, maintenance, design details a.s.o. The study presents the behavior of four machine – foundation systems in a dynamic operating regime. Two of the foundation systems support electric generators groups (CATERPILLAR type), operating at a speed of 1500 rpm, the other two sustaining similar PERKINS models, operating at the same speed. Steady state horizontal and vertical vibration tests were performed on the four foundations. The natural frequencies and amplitudes of vibrations were measured and a comparison between the experimental and required values for the frequencies and vibration amplitudes was carried out.

Experimental Investigations on Four Electric-Generators Foundation Systems

New York, New York

Machinery can affect engineering structures, as well as foundations supporting them and resting directly on the soil. Machines cause distinct dynamic forces depending on its manufacturing purposes, operating conditions, maintenance, design details a.s.o. The study presents the behavior of four machine – foundation systems in a dynamic operating regime. Two of the foundation systems support electric generators groups (CATERPILLAR type), operating at a speed of 1500 rpm, the other two sustaining similar PERKINS models, operating at the same speed. Steady state horizontal and vertical vibration tests were performed on the four foundations. The natural frequencies and amplitudes of vibrations were measured and a comparison between the experimental and required values for the frequencies and vibration amplitudes was carried out.
