Abstract

In diesem Aufsatz wird ein hydraulisches System bestehend aus einem langen Rohr, in dem Wellenausbreitung stattfindet, einem mit einer konstanten Kraft belasteten Hydraulikzylinder, der am Ende des Rohres angeschlossen ist und einem Schaltventil, das den Rohranfang periodisch mit Hoch- und Niederdruck verbindet, untersucht. Ziel ist, die Tauglichkeit dieses Systems als ein Schaltkonverter für hydrostatische Antriebe zu beurteilen. Tauglichkeitskriterien sind der Wirkungsgrad und die Geschwindigkeitsfluktuationen des Kolbens. Der Einfluß der verschiednen Sytemparameter auf diese Kriterien wird behandelt.
