Methods for Determining Undamped Normal Modes and Transfer Functions from Receptance Measurements.
Abstract
Possible approaches to the determination of the dynamic characteristics of a system from receptance measurements are considered. The particular characteristics of interest are transfer functions for which no direct measurements are available, and the undamped normal modes. A simple example, using calculated receptances which are degraded with random errors, indicates the degree of accuracy which might be expected from various methods of analysis. (Author)
