Wir betrachten die Stabilitat gyroskopischer Systeme der Form d 2 u/dt 2 + 2ξG du/dt + (W - ξ 2 K) u = 0 mit G T = -G, W T = W und K > 0 und fur grosse Werte des Parameters ξ > 0. Eine Charakterisierung derjemigen Systeme wird gegeben, die (bei ξ → ∞) stabil unter Storungen sind. Ausserdem werden Resultate uber strenge Stabilitat hergeleitet. Die Berechnung von Stabilitatsintervallen der Art (ξ cr , ∞) wird diskutiert. This paper concerns the stability of gyroscopic systems of the form d 2 u/dt 2 + 2ξG du/dt + (W - ξ 2 K) u = 0, with G T = -G, W T = W, and K > 0, and for large values of the parameter (frequency of rotation) ξ > 0. A complete characterization is given of those limit systems (as ξ → ∞) which are stable after perturbation. Results are also derived concerning strong stability (i.e., when there is stability for the system and all neighbouring systems of the same type) and for computing an upper stability region (ξ cr . ∞).
