Ground‐Based Testing Dynamics for Prismatic Beam in Microgravity
Publication: Journal of Aerospace Engineering
Volume 4, Issue 2
Abstract
Largely because of the high cost of transporting payloads into low Earth orbit, large space structures must first be dynamically analyzed and tested prior to installation in space. The resulting ground‐based test behavior must be correlated to actual behavior in a microgravity environment. This paper will first examine the dynamics of a simple beam on an elastic foundation with, and without, a gravity environment. The same beam is then examined with discrete spring supports in the presence of gravity. The mathematics and solution procedure are described. Resulting theoretical behavior in gravity is compared with the theoretical behavior expected in microgravity.
