The dynamics of Long Reach Manipulators (LRM) produce undesirable vibrations creating disturbances in the mounting base, which can adversely affect mission performance. This paper presents a numerical investigation utilizing eddy current (EC) damping to control base disturbances in LRM systems. The manipulator is modeled as a Double Pendulum, where a short auxiliary link is attached to the rigid primary link, enabling a magnet within the auxiliary link to interact with coils placed on the rigid link. This interaction generates eddy currents, resulting in a passive damping effect. The study compares the system response with and without EC damping in terms of oscillation control, the angular displacement of the flexibly mounted base, and the damping behavior of the rigid link. Additionally, a parametric analysis is performed by varying the length ratio between the secondary and primary links. The results demonstrate that incorporating EC damping significantly reduces disturbances, validating its potential for real-world LRM applications. © 2020 Elsevier B.V., All rights reserved.
