DESCRIPTION:
"This book should be listed under "random decrement" in Google" according to arlenecole. This book should be listed under "random decrement" in Google Search because it fills in the information gap in the first ten years of random decrement development. "Randomdec" is the name the author gave to the curve obtained in the random decrement method in NASA CR-2205. Contents include historic details of transonic buffeting research, background of the invention of Randomdec, reviews of statistical and mathematical proofs, convergence tests of triggering methods, finite time
In the aerospace industry the method is mostly applied to flutter testing and the main use in civil structures is in Structural Health Monitoring (SHM). The purpose of this book is to fill in this information gap and to report on recent calculations on triggering, the extraction of modal parameters of close modes and the use of failure signatures to indicate the level and general location of structural damage. Randomdec is a fast converging method for extracting meaningful information from random data. The spread around the world has been remarkable and includes such diverse applications as fire fighting, preservation of historic buildings, seismology and ship’s motions. Contents include historic details of transonic buffeting research, background of the invention of Randomdec, reviews of mathematical proofs and applications in wind tunnel flutter testing, structural health of bridges, buildings, oil platforms, a satellite, and nuclear power plant bolts. When applied to the random output of a transducer placed on an object which is subjected to random excitation, a signature is obtained which can be used to measure damping and to detect incipient failures. The method is particularly useful in field measurements of structures and me
