Description

Die Erfindung bezieht sich auf ein Prüfstandfundament für Flugmotoren mit einer im Fundament angeordneten schallisolierenden Zwischlenschicht. The invention relates to a test bench foundation for aircraft engines with a sound-insulating intermediate layer arranged in the foundation.

Die Erfindung besteht darin, daß der den Motor tragende Pendelbock auf einem seinen Standockel überragenden Tragrost gelagert und dieser wiederum in Form einer Platte in einer Betonmasse eingebettet ist, die auf der scallisolierenden Schicht ruht. The invention consists in that the pendulum block carrying the motor stored on a supporting grid protruding from its pedestal and this in turn in Form of a plate is embedded in a concrete mass, which is on the scall-isolating Shift rests.

Gegenüber bekanntenm Maschinenfundamentierungen, bei denen zwecks Verhinderung der Übertragung von Erschütterungen an den Grundflächen der Maschine eine, elastische abler druckfeste Zwischenschicht angeordnet ist, wird durch die besondere Anordnung eines Tragrostes in Verbindung mit einem Standsockel für das Fundament und für den Spezialzweck erst eine ausreichende Längsstabilität erzielt. Außerdem wird eine flache und materialsparende Fundamentierung erreicht. Compared to known machine foundations, where for the purpose Prevention of the transmission of vibrations to the base of the machine an elastic abler pressure-resistant intermediate layer is arranged through the special arrangement of a support grid in connection with a pedestal for the Foundation and, for the special purpose, sufficient longitudinal stability is achieved. In addition, a flat and material-saving foundation is achieved.

In (der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. In (the drawing shows an embodiment of the invention.

Abb. 1 zeigt einen Längsschnitt durch den Standsockel mit dem Tragrost und die Betonmasse, die auf einer schallisolierenden Schicht gebettet ist; Abb. 2 zeigt den Grundriß des Standsockels. Fig. 1 shows a longitudinal section through the base with the support grid and the concrete mass, which is bedded on a sound-insulating layer; Fig. 2 shows the floor plan of the pedestal.

Der Motor I mit der Lu, ftschrautbe 2 ist an der Pendelplatte 3 des Bockes 4 frei schwebend aufgehängt. Die an dem Plendielbock gemessenen Werte werden durch entsprechende Leitungen in den Beobachterraum übertragen. Der Piendelbock 4 ist auf einem aus profileisen gefertigten Fundam-entrost 5 befestigt. Der frundamentrost ist wiederum in einem Betonklotz 6 verankert. Der Fundamentrost und der Betonklotz üben zusammen gewichtsmäßig das Gegenmoment zum Propellerzug bzw. The motor I with the air screw 2 is on the pendulum plate 3 of the Bockes 4 suspended freely floating. The values measured on the plendum block are transmitted through appropriate lines in the observer room. The Piendelbock 4 is attached to a foundation rust 5 made of profile iron. The foundation rust is in turn anchored in a concrete block 6. The foundation grate and the concrete block exercise together the counter-torque to the propeller pull resp.

-druck aus. Außerdem gibt der Fundamentrost dem Betonklotz eine zusreichende Längsstabilität. Das gesamte Fundament des Pendelbockes ist außerdem in einer schallisolienenden Schicht 7, z. B. bestehend aus Torfplatten, elastisch eingebettet.-print off. In addition, the foundation grate gives the concrete block sufficient Longitudinal stability. The entire foundation of the pendulum bracket is also in a soundproof Layer 7, e.g. B. consisting of peat slabs, embedded elastically.

Diesei Bett nimmt infolge seiner Elastizität und der geringen spezifischen Pressungen die von dem Pendelbock ausgehenden -me charis chen Schwingungen auf, so daß letztere nicht auf den übrigen Teil Indes Gebäudebodesn 8 übertragen werden können.This bed decreases due to its elasticity and the low specificity Pressing the charical vibrations emanating from the pendulum bracket, so that the latter are not transferred to the remaining part of the building floor 8 can.
