An Impedance Technique for Determining Low-Frequency Payload Environments

摘要

An impedance technique for calculating payload low-frequency environments was derived and demonstrated. The technique is based on frequency domain analysis and eliminates the necessity of final eigensolution for coupled payload/booster systems. A demonstration of the technique using Titan flight data and a low frequency environment prediction for a Shuttle payload are included. Criteria and philosophy for the technique for future payloads is discussed.
