Abstract
This chapter on the recent history of experimental structural dynamics puts much of the Handbook in a historical perspective that begins with the development of digital data methodology and computerized data processing that began in the mid-1960s. Experimental structural dynamics began much earlier with analog, single frequency data acquisition and mostly visual data processing that began in the 1800s with the rail and marine industries, particularly when the steam engine impacted those technologies. The analog, single frequency data acquisition methodology, continued in the automotive and the aircraft industries in the first half of the 1900s. This Handbook mostly chronicles data acquisition and processing methods that began more recently, in the mid-1960s, with the advent of the Fourier transform, analog to digital data conversion, and digital minicomputers to the present time period. The Handbook also discusses many methods and techniques in use during the 1960s and 1970s that utilize experimentally derived models, both linear and nonlinear, to calibrate and validate corresponding analytical models. Part of this discussion includes the issue of the varying dimensionality of the number of degrees of freedom (DOF) between experimental and analytical models. This chapter also discusses the researchers and educators that were part of the development of the experimental structural dynamics methodology in the 1960s to 1980s that led to the current technical state of the art. This discussion includes the identification of researchers and educators that were instrumental to the Society for Experimental Mechanics (SEM) in the development of this area of interest within the Society over the last 50 years.
