Synchronized vibration generators for dynamic tests of full-scale structures

Abstract

The general considerations behind the design of a rotating weight sinusoidal vibration generator for dynamic studies of full-scale structures have been given in a previous report which pointed out the advantages of a system of multiple synchronized machines that would permit a distribution of exciting forces throughout a structure so as to most efficiently excite various modes of vibration. Under the sponsorship of the California State Division of Architecture a set of four synchronized vibration generators has been completed and tested, and the purpose of the present report is to summarize the design information on this new system, and to give detailed operating instructions for its use.
