Methods for the Experimental Determination of Mechanical Mobility - Part I: Basic Definitions and Transducers

This standard is the first part of a series of five standards covering the experimental determination of mechanical mobility of structures by a variety of methods appropriate for different test situations. The present Part I of this series covers basic concepts and definitions and serves as a guide for the selection, calibration, and evaluation of the transducers and instruments used in mobility measurements. The material in Part I is common to most mobility measurement tasks. This document supersedes ANSI Standard S2.6-1963(R1976).  The future parts of this series will cover specific mobility measurement situations such as the use of steady-state rectilinear excitation, steady-state torsionat excitation, measurements of the entire mobility matrix using steady-state excitation, and mobility measurements using impact excitation, as well as other forcing functions which use Fourier transform techniques for data reduction.   The present document (Part I of this series) has four appendices containing selected references to the literature, a discussion of the relationships between mechanical mobility and impedance, a discussion of mobility as a frequency response function, and conversion factors from SI to conventional English units as applicable to mobility and related ratios.
