Abstract

Long-duration human space flights involved by interplanetary journeys or space station missions expose the crews to effects of weightlessness. Such effects, consisting in loss of bone density, skeletal muscle atrophy, cardiovascular deconditioning etc., can raise significant risks on the health of the astronauts and for their capacity to accomplish the missions. Therefore, a large number of studies were dedicated to solutions for creating artificial gravity. The paper studies dynamic effects produced in a tethered two-spacecraft system, with artificial gravity produced by rotation motion. One of the spacecrafts is the habitable module, while the other is a service module. The system is modeled by two rigid bodies connected by a tether with negligible mass. The system travels on a circular circumterrestrial orbit, while the two rigid bodies rotate about the center of mass. The effect of the centrifugal forces produced on the rigid bodies simulates gravity conditions. Due to the viscoelastic behavior of the tether, several oscillating phenomena occur. The variations of the main parameters of the system determined by these oscillations are assessed and considerations are made upon the energy dissipation.
