Abstract:
Die Erfindung betrifft einen Schwingungstilger bzw. - dämpfer, der mit Hilfe einer Blattfeder, deren physikalisch wirksame Länge variabel gestaltet ist, über einen bestimmten Bereich an die in einer bestimmten Richtung wirkenden Störsequenzen eines zu dämpfenden Bauteils bzw. der zu dämpfenden Maschine oder Anlage angepasst werden kann. Die Erfindung betrifft insbesondere einen Schwingungstilger, der selbst weitgehend ungedämpft ist, so dass hier größere Amplituden und somit größere Kräfte erzielt werden können. Der erfindungsgemäße Dämpfer ist, insbesondere zur Reduzierung des Körperschalls in Anlagen und Maschinen, vorzugsweise Windkraftanlagen, geeignet, welche häufige Drehzahländerungen unterworfen sind und so in Schwingungen geraten.

Abstract:
A mechanical device for use in the control of mechanical forces. The device comprising first and second terminals which, in use, are connected to components in a system for controlling mechanical forces. These terminals are moveable with respect to one another. The device further comprises means connected between the terminals to control the mechanical forces at the terminals. These mechanical forces are proportional to the relative acceleration between the terminals, wherein the proportionality term is either a fixed constant or a variable function.
