Abstract :
A study was made of the vibration characteristics of a model vibrating system with a permanent magnet/HTSC damper. Both free and forced vibration techniques were used. The damping factor was found to decrease at small vibration amplitudes due to small flux penetration depth at low applied oscillating fields. The HTSC samples showed both hysteresis and flux-flow types of energy losses in damping unit. The measured resonance characteristic was typical of a nonlinear vibrating system.
