Description

Die Erfindung betrifft ein Unterseeboot mit einem aktiven Schwingungsdämpfer.The invention relates to a submarine with an active vibration damper.

Bei militärischen Unterseebooten ist von dem Unterseeboot ausgehender Schall möglichst gering zu halten, da getauchte Unterseeboote über den sich im Wasser ausbreitenden Schall geortet werden können. In umgekehrter Weise sind Unterseeboote während der Tauchfahrt in der Lage, Überwasserfahrzeuge über den von diesen Fahrzeugen auf das Wasser übertragenen Schall zu orten, sodass auch bei militärischen Überwasserfahrzeugen das Bedürfnis besteht, den von Ihnen ausgehenden Wasserschall möglichst gering zu halten. Hierbei kommt der Verringerung des Körperschalls, der von den auf den Wasserfahrzeugen befindlichen schwingungserzeugenden Vorrichtungen hervorgerufen wird und über die Tragstruktur des Wasserfahrzeugs zu dessen Außenhülle geleitet wird, eine besondere Bedeutung zu.In the case of military submarines, the sound emanating from the submarine must be kept as low as possible, since submerged submersibles can be located using the sound propagating in the water. Conversely, submarines are able to locate surface vehicles via the sound transmitted by these vehicles to the water during the dive, so that even with military surface vehicles there is a need to keep the water sound emitted by you as low as possible. The reduction in structure-borne noise, which is caused by the vibration-generating devices located on the watercraft and is conducted via the support structure of the watercraft to its outer shell, is of particular importance.

Dokumente WO 90/10926 A1 und DE 102 23 965 A1 beschreiben jeweils ein Unterseeboot mit einem aktiven Schwingungsdämpfer zur Kompensation von Körperschall. Aus der DE 3642747 A1 ist ein Unterseeboot bekannt, das einen Hüllkörper für eine Hydrophonanordnung aufweist.Documents WO 90/10926 A1 and DE 102 23 965 A1 each describe a submarine with an active vibration damper to compensate for structure-borne noise. From the DE 3642747 A1 a submarine is known which has an envelope for a hydrophone arrangement.

Vor diesem Hintergrund besteht die Aufgabe der Erfindung darin, ein Unterseeboot zu schaffen, bei dem ein durch die Einleitung von Körperschall in die Tragstruktur verursachter Wasserschall möglichst vollständig verhindert, zumindest aber im größtmöglichen Maße verringert wird.Against this background, the object of the invention is to create a submarine in which water noise caused by the introduction of structure-borne noise into the supporting structure is prevented as completely as possible, but is at least reduced to the greatest possible extent.

Diese Aufgabe wird durch ein Unterseeboot mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen dieses Unterseeboots ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung sowie aus der Zeichnung.This object is achieved by a submarine with the features specified in claim 1. Advantageous further developments of this submarine result from the subclaims, the following description and from the drawing.

Das erfindungsgemäße Unterseeboot weist in üblicher Weise eine mit der Wasserumgebung in Kontakt stehende Tragstruktur auf. Hierbei sind unter dem Begriff "Tragstruktur" alle direkt oder indirekt miteinander verbundenen tragenden Teile des Rumpfes und der Aufbauten des Wasserfahrzeugs sowie insbesondere eine mit dem Umgebungswasser in Kontakt stehende tragende Außenhülle des Wasserfahrzeugs zu verstehen. Um den von auf der Tragstruktur gelagerten schwingungserzeugenden Vorrichtungen, wie z. B. Motoren, Pumpen oder Kompressoren, auf die Tragstruktur übertragenen Körperschall zu kompensieren, ist das Wasserfahrzeug mit Mitteln zur Kompensation von Körperschall ausgestattet. Mit diesen Mitteln wird die von den schwingungserzeugenden Vorrichtungen in die Tragstruktur eingeleitete Schwingungsenergie zumindest teilweise kompensiert, indem in die Tragstruktur Schwingungen eingeleitet werden, welche die von den schwingungserzeugenden Vorrichtungen in die Tragstruktur eingeleiteten Schwingungen mittels destruktiver Interferenz größtenteils und günstigstenfalls vollständig auslöschen.The submarine according to the invention has a support structure which is in contact with the water environment in the usual way. Here are under the term "Support structure" to understand all directly or indirectly connected supporting parts of the hull and the superstructure of the watercraft as well as in particular a supporting outer shell of the watercraft that is in contact with the surrounding water. To the vibration generating on the support structure Devices such. B. engines, pumps or compressors to compensate for structure-borne noise transmitted to the supporting structure, the watercraft is equipped with means for compensating structure-borne noise. With these means, the vibration energy introduced into the support structure by the vibration-generating devices is at least partially compensated for by introducing vibrations into the support structure, which largely and, at best, completely cancel out the vibrations introduced by the vibration-generating devices into the support structure by means of destructive interference.

Die wesentliche Idee der Erfindung besteht darin, die Mittel zur Kompensation von Körperschall auf der Grundlage des von dem Körperschall an der Außenhülle des Wasserfahrzeugs hervorgerufenen Wasserschalls zu steuern. Zu diesem Zweck weist das erfindungsgemäße Unterseeboot ein Hydrophon auf, welches mit einer Einrichtung zur Steuerung der Mittel zur Kompensation von Körperschallsignal verbunden ist. Das Hydrophon erfasst genau das von der Außenhülle aufgrund dessen Körperschallanregung ausgehende Geräusch, welches sich im Wasser über große Strecken ausbreitet und ohne die Kompensation durch die Mittel zur Kompensation von Körperschall zu einer Ortung des Wasserfahrzeugs führen könnte. Es hat sich gezeigt, dass sich der Wasserschall durch die Verwendung von Mitteln zur Kompensation von Körperschall und deren Steuerung auf Grundlage des von dem Hydrophon erfassten Wasserschalls signifikant verringern und bestenfalls auslöschen lässt.The essential idea of the invention is to control the means for compensating structure-borne noise on the basis of the water-borne noise caused by the structure-borne noise on the outer shell of the watercraft. For this purpose, the submarine according to the invention has a hydrophone which is connected to a device for controlling the means for compensating structure-borne noise. The hydrophone precisely detects the noise emitted by the outer shell due to its structure-borne noise excitation, which spreads over long distances in the water and could lead to a location of the watercraft without the compensation by means of structure-borne noise compensation. It has been shown that the use of means for compensating for structure-borne noise and their control on the basis of the water sound detected by the hydrophone can significantly reduce and at best cancel out the water sound.

Als Mittel zur Kompensation von Körperschall ist erfindungsgemäß mindestens ein aktiver Schwingungsdämpfer vorgesehen. Hierbei ist unter einem aktiven Schwingungsdämpfer ein Krafterreger zu verstehen, mit dem in der Tragstruktur aktiv Schwingungen erzeugt werden, welche mit den von einer schwingungserzeugenden Vorrichtung in die Tragstruktur eingeleiteten Schwingungen frequenz- und amplitudengleich, jedoch um 180° phasenverschoben sind, sodass sich die von dem Krafterreger in die Tragstruktur eingeleiteten Schwingungen und die von der schwingungserzeugenden Vorrichtung in die Tragstruktur eingeleiteten Schwingungen soweit gegenseitig eliminieren, dass in der Wasserumgebung des Wasserfahrzeugs möglichst kein Wasserschall verursacht wird. Neben der Verwendung eines aktiven Schwingungsdämpfers können als Mittel zur Kompensation von Körperschall auch alle weiteren Vorrichtungen verwendet werden, mit denen Schwingungen hinsichtlich ihrer Frequenz, Amplitude und Phase gesteuert in die Tragstruktur eingeleitet werden können. So kann als Mittel zur Kompensation von Körperschall gegebenenfalls auch ein mit der Tragstruktur gekoppelter Rüttelmotor vorgesehen sein.According to the invention, at least one active vibration damper is provided as a means for compensating structure-borne noise. Here, an active vibration damper is to be understood as a force exciter with which vibrations are actively generated in the support structure, which are frequency and amplitude-equal, but are phase-shifted by 180 ° with the vibrations introduced into the support structure by a vibration-generating device, so that those of the Force mutations in the support structure introduced vibrations and the vibrations introduced into the support structure by the vibration-generating device mutually so far that no water noise is caused in the water environment of the watercraft. In addition to the use of an active vibration damper, all other devices can also be used as means for compensating structure-borne noise, with which vibrations can be introduced into the support structure in a controlled manner with regard to their frequency, amplitude and phase. For example, a vibration motor coupled to the support structure can also be provided as a means for compensating structure-borne noise.

Um mit den Mitteln zur Kompensation von Körperschall, die zur Eliminierung der von der schwingungserzeugenden Vorrichtung in die Tragstruktur eingeleiteten Körperschallschwingungen erforderlichen Gegenschwingungen in die Tragstruktur einleiten oder dort erzeugen zu können, sind die Mittel zur Kompensation von Körperschall zweckmäßigerweise in Wirkkontakt mit der Tragstruktur angeordnet. So kann beispielsweise bei Verwendung eines aktiven Schwingungsdämpfers dessen Krafterreger derart außenseitig der Tragstruktur angeordnet sein, dass er direkt eine Erregerkraft zur Erzeugung der Gegenschwingungen auf die Tragstruktur ausüben kann.In order to be able to use the means for compensating structure-borne noise to initiate or generate counter-vibrations necessary to eliminate the structure-borne sound vibrations introduced into the support structure by the vibration-generating device, the means for compensating structure-borne noise are expediently arranged in active contact with the support structure. For example, when an active vibration damper is used, its force exciter can be arranged on the outside of the support structure in such a way that it can exert an excitation force directly on the support structure to generate the counter-vibrations.

Erfindungsgemäß handelt es sich bei dem Wasserfahrzeug um ein Unterseeboot, bei dem sich die erfindungsgemäß vorgesehenen Maßnahmen zur Eliminierung bzw. Verringerung des durch die Einleitung von Körperschall in die Tragstruktur verursachten Wasserschalls als besonders nützlich erweisen.
Bei einem Unterseeboot bildet der Druckkörper den Teil der Tragstruktur des Bootes, welcher direkt an dessen Wasserumgebung angrenzt und an welchem über eine Körperschallanregung erzeugter Wasserschall entsteht. Insofern ist das Hydrophon außerhalb des Druckkörpers des Unterseeboots angeordnet, wo es in direktem Kontakt zu dem Umgebungswasser des Unterseeboots steht und den Wasserschall direkt erfassen kann.
Unterseeboote weisen typischerweise eine in Teilbereichen von dem Druckkörper beabstandete Außenhaut auf, wobei der Zwischenraum zwischen der Außenhaut und dem Druckkörper wasserdurchflutet ist.According to the invention, the watercraft is a submarine in which the measures provided according to the invention for eliminating or reducing the waterborne noise caused by the introduction of structure-borne noise into the supporting structure prove to be particularly useful.
In the case of a submarine, the pressure hull forms the part of the support structure of the boat that is directly adjacent to its water environment and on which water sound is generated by means of structure-borne sound excitation. In this respect, the hydrophone is arranged outside the pressure hull of the submarine, where it is in direct contact with the ambient water of the submarine and can directly detect the water sound.
Submarines typically have an outer skin spaced apart from the pressure body in partial areas, the space between the outer skin and the pressure body being flooded with water.

Erfindungsgemäß ist das Hydrophon innerhalb dieses von der Außenhaut des Unterseeboots umschlossenen, wasserdurchfluteten Bereichs des Unterseeboots angeordnet. D. h. das Hydrophon wird in dem Zwischenraum zwischen dem Druckkörper und der Außenhaut angeordnet, wobei es außenseitig von der Außenhaut abgedeckt wird, die den Druckkörper des Unterseeboots und/oder an dem Druckkörper ausgebildete Aufbauten des Unterseeboots strömungsgünstig verkleidet. Das Hydrophon wirkt sich somit nicht auf die Strömungseigenschaften des Unterseeboots aus und wird von der Außenhaut vor äußeren Einflüssen geschützt.
Nachfolgend ist die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. In der Zeichnung zeigt:

  • Fig. 1 in einer stark vereinfachten Prinzipskizze ein nicht unter die Erfindung fallendes Überwasserschiff und
  • Fig. 2 in einer stark vereinfachten Prinzipskizze ein Unterseeboot.
According to the invention, the hydrophone is arranged within this water-flooded area of the submarine, which is surrounded by the outer skin of the submarine. That is, the hydrophone is arranged in the space between the pressure body and the outer skin, wherein it is covered on the outside by the outer skin, which streamlines the pressure body of the submarine and / or superstructures of the submarine formed on the pressure body. The hydrophone thus has no effect on the flow properties of the submarine and is protected by the outer skin from external influences.
The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the drawing. The drawing shows:
  • Fig. 1 in a greatly simplified schematic diagram a surface ship not falling under the invention and
  • Fig. 2 a submarine in a very simplified outline.

Ein in Fig. 1 dargestelltes Überwasserschiff 2 weist eine Tragstruktur 4 auf, welche alle tragenden Teile des Schiffskörpers beinhaltet, die aber in Fig. 1 sehr stark vereinfacht lediglich in Form eines Schiffsrumpfes 6 und eines mit dem Schiffsrumpf 6 in Verbindung stehenden Trägers 8 dargestellt ist. Auf der Tragstruktur 4 ist eine Vorrichtung 10 gelagert, welche in Fig. 1 durch den Pfeil 12 deutlich gemachte Schwingungen ausführt.
Diese Schwingungen führen innerhalb der Tragstruktur 4 zu Körperschall, welcher sich bis in den Schiffsrumpf 6 ausbreitet, wo er in einem unterhalb der Wasseroberfläche 14 befindlichen Bereich Wasserschall 16 verursacht. Um diesen Wasserschall 16 zu eliminieren oder zumindest deutlich zu verringern, ist ein mit der Tragstruktur 4 in Wirkkontakt stehender aktiver Schwingungsdämpfer 18 vorgesehen, dessen Krafterreger derart von einer Steuerungseinrichtung 20 angesteuert wird, dass eine von dem Krafterreger auf die Tragstruktur 4 ausgeübte Erregerkraft in der Tragstruktur aktiv Schwingungen erzeugt, welche mit den von der Vorrichtung 10 in die Tragstruktur 4 eingeleiteten Schwingungen frequenz- und amplitudengleich sind, jedoch eine entgegengesetzte Polarität aufweisen, sodass sich die von dem Krafterreger in die Tragstruktur 4 eingeleiteten Schwingungen und die von der Vorrichtung 10 in die Tragstruktur 2 eingeleiteten Schwingungen soweit gegenseitig auslöschen, dass in der Wasserumgebung des Überwasserschiffs 2 möglichst kein Wasserschall 16 wahrnehmbar ist.
Die Steuerung des aktiven Schwingungsdämpfers 18 erfolgt auf der Grundlage des in der Außenumgebung des Überwasserschiffs 2 wahrnehmbaren Wasserschalls 16, der durch Schwingungen der Vorrichtung 10 verursacht wird. Zur Erfassung des Wasserschalls 16 ist an der mit dem Umgebungswasser des Schiffs in Kontakt stehenden Seite des Schiffsrumpfs 6 unterhalb der Wasserlinie 14 ein Hydrophon 22 angeordnet, welches mit der Steuerungseinrichtung 20 signalverbunden ist. Basierend auf den von dem Hydrophon 22 zur Verfügung gestellten Signalen wird der Schwingungsdämpfer 18 derart angesteuert, dass die von dem Krafterreger des Schwingungsdämpfers 18 in die Tragstruktur erzeugten Gegenschwingungen die von der Vorrichtung 10 erzeugten Schwingungen so weit eliminieren, dass außerhalb des Schiffsrumpfes 6 kein Wasserschall 16 wahrnehmbar ist.An in Fig. 1 The surface ship 2 shown has a supporting structure 4 which contains all the supporting parts of the hull, but which is shown in FIG Fig. 1 is shown in a very simplified manner only in the form of a ship's hull 6 and a carrier 8 connected to the ship's hull 6. On the support structure 4, a device 10 is mounted, which in Fig. 1 vibrations made clear by arrow 12.
These vibrations lead to structure-borne noise within the support structure 4, which propagates into the ship's hull 6, where it causes water-borne noise 16 in an area below the water surface 14. In order to eliminate or at least significantly reduce this water sound 16, an active vibration damper 18, which is in active contact with the support structure 4, is provided, the force exciter of which is controlled by a control device 20 in such a way that an excitation force exerted by the force exciter on the support structure 4 in the support structure actively generates vibrations which are of the same frequency and amplitude with the vibrations introduced into the supporting structure 4 by the device 10, but have an opposite polarity, so that the vibrations introduced into the supporting structure 4 by the force exciter and those from the device 10 into the supporting structure 2 so far cancel each other out that vibrations are initiated that in the water environment of the surface ship 2 there is as far as possible no water sound 16 perceptible.
The control of the active vibration damper 18 takes place on the basis of the water sound 16 that is perceptible in the external environment of the surface ship 2 Vibrations of the device 10 is caused. To record the water sound 16, a hydrophone 22, which is signal-connected to the control device 20, is arranged below the water line 14 on the side of the hull 6 in contact with the ambient water of the ship. Based on the signals provided by the hydrophone 22, the vibration damper 18 is controlled in such a way that the counter-vibrations generated by the force exciter of the vibration damper 18 in the supporting structure eliminate the vibrations generated by the device 10 to such an extent that no water sound 16 outside the ship's hull 6 is noticeable.

In Fig. 2 ist ein erfindungsgemäßes Unterseeboot 24 dargestellt, das einen Druckkörper 26 aufweist, welcher außenumfänglich zumindest in einem Teilbereich von einer von dem Druckkörper 26 beabstandeten Außenhaut 28 umgeben ist. Hierbei ist ein Zwischenraum 30 zwischen dem Druckkörper 26 und der Außenhaut 28 wasserdurchflutet.
Der Druckkörper 26 bildet zusammen mit allen in dem Druckkörper 26 befindlichen tragenden Teilen eine Tragstruktur 4', wobei die Tragstruktur 4' in Fig. 2 sehr stark vereinfacht lediglich durch den Druckkörper 26 und einen Träger 8' veranschaulicht ist. Auch in dem Unterseeboot 24 ist auf der Tragstruktur 4' zumindest eine Vorrichtung 10' gelagert, welche durch den Pfeil 12 symbolisierte Schwingungen ausführt, die in der Tragstruktur 4' Körperschall und außenseitig des Druckkörpers 26 Wasserschall erzeugen.
Um diesen Wasserschall zu verhindern oder zumindest deutlich zu verringern, weist auch das Unterseeboot 24 einen mit der Tragstruktur 4' in Wirkkontakt stehenden aktiven Schwingungsdämpfer 18 auf, der von einer Steuerungseinrichtung 20 gesteuert wird, wobei die Steuerung des Schwingungsdämpfers 18 auch auf der Grundlage des von einem mit der Steuerungseinrichtung 20 signalverbundenen Hydrophons 22 erfassten Wasserschalls erfolgt. Das Hydrophon 22 ist erfindungsgemäß in dem wasserdurchfluteten Zwischenraum 30 zwischen dem Druckkörper 26 und der Außenhaut 28 des Unterseeboots 24 angeordnet, wo es sich nicht auf die Strömungseigenschaften des Unterseeboots auswirkt und von der Außenhaut 28 vor äußeren Einflüssen geschützt ist. Der an dem Unterseeboot 24 eingesetzte aktive Schwingungsdämpfer, die Steuerungseinrichtung 20 und das Hydrophon 22 können den entsprechenden in dem in Fig. 1 dargestellten Überwasserschiff 2 verwendeten Komponenten entsprechen, wobei aber hinsichtlich des Hydrophons 22 sicherzustellen ist, dass es bei der größtmöglichen Tauchtiefe des Unterseeboots 24 druckfest ist.In Fig. 2 A submarine 24 according to the invention is shown, which has a pressure body 26, which is surrounded on the outside at least in a partial area by an outer skin 28 spaced apart from the pressure body 26. Here, an intermediate space 30 between the pressure body 26 and the outer skin 28 is flooded with water.
The pressure body 26 forms, together with all the supporting parts located in the pressure body 26, a support structure 4 ', the support structure 4' in Fig. 2 is illustrated in a very simplified manner only by the pressure body 26 and a carrier 8 '. Also in the submarine 24, at least one device 10 'is mounted on the support structure 4', which executes vibrations symbolized by the arrow 12, which generate structure-borne noise in the support structure 4 'and 26 outside water pressure.
In order to prevent or at least significantly reduce this water sound, the submarine 24 also has an active vibration damper 18 which is in active contact with the supporting structure 4 ′ and is controlled by a control device 20, the control of the vibration damper 18 also being based on the a water sound recorded with the control device 20 hydrophones 22. According to the invention, the hydrophone 22 is arranged in the water-flooded intermediate space 30 between the pressure body 26 and the outer skin 28 of the submarine 24, where it does not affect the flow properties of the submarine and is protected from external influences by the outer skin 28. The active vibration damper used on the submarine 24, the control device 20 and the hydrophone 22 can be used in the corresponding in the Fig. 1 Components shown surface ship 2 used, but it must be ensured with regard to the hydrophone 22 that it is pressure-resistant at the greatest possible depth of the submarine 24.
