Abstract

Elastic properties of manoeuvring object orbiting earth is discussed herein. Deflections in an elastic beam produced as a result of its motion and external forces are determined using Kane’s dynamical equations. Inertia, internal, control, and gravity forces are included to develop modes shapes of vibrations. Deflections at end points are then determined, consequently mass centre position along with beam orientation is amended to have precise positions of end point, where docking with other objects are attained.
