Passive Damping

Passive damping is a technique used in space and astronautical engineering to reduce the vibrations and oscillations of a spacecraft or satellite without the need for external energy input. This is achieved by incorporating materials or devices that dissipate the energy of the vibrations, such as viscoelastic materials or tuned mass dampers. Passive damping is particularly important in space applications where active control systems may not be feasible due to power or weight constraints, or where redundancy is required to ensure mission success. The effectiveness of passive damping depends on the design and placement of the damping elements, as well as the frequency and amplitude of the vibrations.
