CALCULATION OF ELASTIC-DAMPING CHARACTERISTICS OF MULTI-LAYER STEEL STRIPE VIBRATION ISOLATORS

Theoretical and experimental research on multi-layer steel plates isolator are exploited.The relationship between the thickness, width， number of layers, radius, numbers of the rings, stiff-ness, in ner friction force, energy dissipation coefficient of isolator are derived, and a mathematic model of hysteresis loop of isolator is obtained. Experimental results show that the calculation equation and mathematic model of hysteresis loop can satisfy with experimental results very well.
