The Effects of Small Horizontal Vibrations of the Mother Ship on Tethered Systems with Changing Length

EasyChair Preprint 13597

Abstract

A tethered system represents a flexible multi-body system in which components and bodies such as a mothership, probes and equipment, are connected by flexible tether cable. When using such a system, it is assumed that the mothership moves harmonically while changing the tether length. This can cause the system resonance while being affected by ' the spaghetti problem', which is the problem involves the instability with oscillations of a flexible body. In this study, the effects of small vibrations of the mother ship on a tethered system during changing the tether length are studied and the indicators for these phenomena are proposed.

Keyphrases: Absolute nodal coordinate system, Multibody System Dynamics, flexible body, resonance
