Abstract
Non-Linear Passive Dampers (NLPDs) have been developed for micorgravity experiment. The LNPD is comprised of flexible membranes and connecting rods, and the damping is performed under microgravity utilizing the non-linear elasticity of flexible membranes. The damper is small and simple in construction and it does not consume any electric power. A prototype damper and improved one have been developed and the performances are verified by microgravity experiments using an airplane. The performance of the damper is investigated for utilizing in the Space Station.
