Description
Die Erfindung bezieht sich auf ein Verfahren zum Überprüfen eines Drehschwingungsdämpfers mit einem an eine Welle anschließbaren Anschlußteil und einer mit dem Anschlußteil drehelastisch verbundene seismische Drehmasse, wobei die Drehwinkel sowohl des Anschlußteils als auch der seismischem Drehmasse digital gemessen und in einer Rechenstufe zur Ausgabe eines Kennwertes verrechnet werden.The The invention relates to a method for checking a torsional vibration damper a connectable to a shaft Connection part and one with the connection part torsionally elastic connected seismic rotating mass, wherein the rotation angle both of the connector as well as the seismic rotating mass digitally measured and in one Calculation level to output a characteristic value are calculated.
In
Antriebssträngen,
in denen Drehschwingungen auftreten, wie dies beispielsweise bei
Antriebssträngen
mit Verbrennungsmotoren der Fall ist, werden Drehschwingungsdämpfer eingesetzt,
die die Drehschwingungen und damit die auftretenden Belastungen
der Antriebsteile durch Drehwechselspannungen auf ein zulässiges Maß begrenzen.
Der unbeeinträchtigten
Funktion der Schwingungsdämpfer kommt
daher in solchen Antriebssträngen
eine große Bedeutung
zu, so daß zumindest
in besonderen Fällen
die Drehschwingungsdämpfer
laufend überwacht werden.
Zu diesem Zweck ist es bekannt (
Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren zum Überprüfen eines Drehschwingungsdämpfers der eingangs geschilderten Art so auszugestalten, daß mit einem vergleichsweise geringen Aufwand die Torsionssteifigkeit und die Torsionsdämpfung des Drehschwingungsdämpfers mit der notwendigen Genauigkeit als Kennwerte für die Überprüfung erfaßt werden können.Of the Invention is therefore the object of a method for checking a torsional vibration damper the type described above in such a way that with a the torsional rigidity and the torsional damping of the comparatively small expenditure Torsional vibration damper with the necessary accuracy can be detected as characteristic values for the check.
Die Erfindung löst die gestellte Aufgabe dadurch, daß aus den zeitsynchron gemessenen Drehwinkeln des Anschlußteils und der seismischen Drehmasse einerseits der relative Verdrehwinkel zwischen diesen beiden Teilen und anderseits die Drehwinkelbeschleunigungen der seismischen Drehmasse unter Berücksichtigung allfälliger Änderungen der Winkelgeschwindigkeit des Anschlußteils ermittelt und daraus mit Hilfe des konstruktiv vorgegebenen Massenträgheitsmomentes der seismischen Drehmasse die Torsionssteifigkeit und die Torsionsdämpfung als Kennwerte errechnet und angezeigt werden.The Invention solves the task posed by the fact that measured from the time-synchronous Rotation angles of the connection part and the seismic rotating mass on the one hand, the relative angle of rotation between these two parts and on the other hand the rotational angular accelerations the seismic rotating mass taking into account any changes the angular velocity of the connector determined and from it with the help of the constructive mass moment of inertia of the seismic Torque the torsional stiffness and torsional damping as Characteristic values are calculated and displayed.
Die Erfindung geht von der Erkenntnis aus, daß bei einer ausreichend genauen zeitsynchronen Messung der Drehwinkel des Anschlußteils und der seismischen Drehmasse nicht nur in an sich bekannter Weise der relative Verdrehwinkel zwi schen diesen beiden Teilen des Drehschwingungsdämpfers berechnet, sondern zusätzlich die jeweilige Drehwinkelbeschleunigung der seismischen Drehmasse bestimmt werden kann, um aus dem bekannten Zusammenhang zwischen der Drehwinkelbeschleunigung und dem Massenträgheitsmoment der seismischen Drehmasse das jeweils wirksame Drehmoment zu berechnen, das in Abhängigkeit von dem im Meßzeitpunkt gegebenen Verdrehwinkel zwischen dem Anschlußteil und der seismischen Drehmasse des Drehschwingungsdämpfers zur Berechnung der Torsionssteifigkeit und der Torsionsdämpfung des Drehschwingungsdämpfers in einer Rechenstufe genützt werden kann, die die jeweils berechneten Istwerte dieser Kenngrößen an eine Anzeigeeinrichtung ausgibt.The Invention is based on the recognition that with a sufficiently accurate time-synchronous measurement of the rotation angle of the connection part and the seismic rotating mass not only in a conventional manner the relative angle of rotation calculated between these two parts of the torsional vibration damper, but in addition the respective rotational angular acceleration of the seismic rotating mass can be determined from the known relationship between the rotational angular acceleration and the mass moment of inertia of the seismic rotating mass to calculate the respective effective torque, depending on from that at the time of measurement given angle of rotation between the connecting part and the seismic rotating mass of the torsional vibration damper for the calculation of the torsional rigidity and the torsional damping of the torsional vibration damper be used in a computing stage can, which the respective calculated actual values of these characteristics to a Display device outputs.
Da es für die Bestimmung der Torsionssteifigkeit und der Torsionsämpfung auf eine genaue zeitsynchrone Erfassung der Drehwinkel und der davon abhängigen, auf die Drehschwingungen bezogenen Winkelgeschwindigkeiten ankommt, müssen entsprechende Einflüsse beispielsweise aufgrund einer Drehzahlsteigerung der Antriebswelle berücksichtigt werden, was anhand einer Frequenzanalyse der Meßsignale vorgenommen werden kann, um beispielsweise entsprechende Frequenzen aus den Meßsignalen auszufiltern. Die hiefür eingesetzten Filter dürfen jedoch zu keiner Phasenverschiebung der für die Auswertung der Meßergebnisse in der Rechenstufe benötigten Signalkomponenten führen.Since it depends on an accurate time-synchronous detection of the rotation angle and the dependent on the torsional vibrations related angular velocities for the determination of the torsional stiffness and torsion, corresponding influences must be taken into account, for example due to an increase in rotational speed of the drive shaft, which can be done by a frequency analysis of the measurement signals For example, to filter out corresponding frequencies from the measured signals. The used fil ter, however, must not lead to a phase shift of the signal components required for the evaluation of the measurement results in the computing stage.
