In this paper, the motion of a tethered system with large deformation and large displacement is discussed experimentally. A tethered subsatellite in space is well known as an example of this system. However, even fundamental experiments about the motion of the tethered system have not been done. Also in a viewpoint of flexible mulutibody dynamics, it is expected that simple experiments for a motion of very flexible body are completed in order to verify the validity of the proposed approach. In this study, a system consisting of a very flexible body and a rigid body is regarded as the tethered system. First, we conducted an experiment about fundamental motion of a very flexible body with a attached mass in gravity space. We select steel and rubber as the tether material. In these experimental results, the characteristics of the complex motion of a very flexible body are obtained. Second a experiment in micro gravity space was done. The coupled motion between the very flexible body and rigid body is investigated. It is verified that the motion of the system with large deformation excited in micro gravity space and the interaction between the deflection of the very flexible body and the rotation of the rigid body.
