Standardized Procedure for Experimental Vibration Testing of Damping Test Specimens.

Abstract

The experimental determination of structural or material damping as a function of frequency can be a complicated task. The observed values can apparently change between experiments. This report includes a proposed standardized test procedure which aims to reduce these variations in modal damping. The standard focuses on the four main areas where variations in test procedure can introduce differences: a) preparation and support of the structure; b) selection, preparation and use of transducers and equipment; c) setting up the analyzer, and d) data analysis and reduction.
