This document provides guidance to select a vibration generator that will be used to evaluate frequency
responses of a test structure or to study how vibration grows/decreases along the structure. These
structural dynamics tests can be carried out under field or laboratory conditions (see the ISO 7626 or
ISO 10846[4][5][6][7]series).
This document describes the selection procedure in terms of the force developed by a single vibration
generator. Meanwhile, to move massive structures such as dams or bridges, an assembly of vibration
generators is usually applied. Properly phased generators produce in total the same force as calculated
for a single vibration generator (see 6.2.6).
Guidance also can be applied for the selection of equipment to be used for modal testing to determine
natural frequencies, modal shapes and damping in a structure; however, for such a test, more factors
than covered by this document usually need to be considered.
This document deals only with translational excitation. For equipment applied to generate angular
vibration, see Reference [8].Cross References:ISO 15261ISO 10846-1ISO 7626-1ISO 2041ISO 10846-5ISO 7626-5ISO 7626-2ISO 10846-3ISO 10846-4ISO 10813-1ISO 10846-2All current amendments available at time of purchase are included with the purchase of this document.
