The Validity of the Single Degree of Freedom System Analog for Vibration Analysis

摘要

A series of electrical analogs, each of which had the properties of a mechanical single degree of freedom system at a given frequency with control over 'Q' were designed and constructed at APL for the purpose of vibration analysis. This report presents test results showing the degree of accuracy that may be obtained from these analogs using the analysis techniques outlined. It was initially assumed that the flight vibration was a stochastic function.
