Description

  • The present invention relates to a Helmholtz resonator for damping airborne sound in a room, in particular in an airborne sounding conduit. The invention also relates to a gas-conducting system for an internal combustion engine, in particular of a motor vehicle, as well as a silencer for such a gas-conducting system, which are each equipped with such a Helmholtz resonator.
  • A Helmholtz resonator is well known in the acoustics and serves to dampen airborne sound. For example, such Helmholtz resonators are used in fresh air systems and exhaust systems of internal combustion engines, in particular in motor vehicles, in order to selectively dampen certain interfering frequencies. Usually, a Helmholtz resonator has a resonant volume which is enclosed in a housing and which communicates via a neck with the space in which the sound to be damped propagates. The Helmholtz resonator acts like a spring-mass oscillator whose spring is formed by the resonance volume and whose mass is formed by the air mass oscillating in the neck. Such Helmholtz resonators can be calculated comparatively accurately and interpreted accordingly relatively accurately. In principle, they can only be interpreted to a certain resonance frequency, which is comparatively low. In principle, it is also conceivable to connect a common resonance volume via two different necks with the space to be damped, as a result of which the Helmholtz resonator has two different resonance frequencies. From the WO 02/082859 is a Helmholtz resonator with membrane known.
  • The present invention is concerned with the problem for a Helmholtz resonator of the type mentioned or for a so equipped Gas management system or a so equipped muffler to provide an improved embodiment, which is characterized in particular by the fact that with a relatively low cost at least two different resonant frequencies can be realized.
  • This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.
  • The invention is based on the general idea of equipping the housing of the Helmholtz resonator with at least one oscillatable membrane which is designed such that its first order resonant frequency essentially corresponds to that resonant frequency that a structurally identical Helmholtz resonator would have without such a membrane. This construction has the consequence that the membrane is excited to vibrate in the region of its resonant frequency, which slightly attenuates the damping effect of the Helmholtz resonator in the region of the resonant frequency compared to a structurally identical Helmholtz resonator without such a membrane, but in a first frequency range adjacent thereto , which lies below the resonant frequency of the membrane, as well as in a second frequency range adjacent thereto, which is above the resonant frequency of the membrane, each showing a maximum of the damping effect, in these two frequency ranges compared to a structurally identical Helmholtz resonator without such a significant membrane show increased damping effect. The Helmholtz resonator constructed according to the invention thus has two different frequencies with maximum damping effect on both sides of the resonant frequency of the diaphragm. These two frequencies thus form two resonance frequencies of the Helmholtz resonator according to the invention. They can be predicted comparatively accurately. By the two Resonant frequencies, the proposed Helmholtz resonator receives a certain broadband effect, namely between its resonance frequencies. The Helmholtz resonator thus formed can be effectively used in particular also in varying environmental conditions.
  • According to an advantageous embodiment, the housing may have at least one cover which encloses the wall section having the membrane in an additional volume, in particular gas-tight, at an outer side of the housing facing away from the resonance volume. In this way, the damping effect of the membrane to a certain extent of environmental conditions, such. For example, pressure and temperature, the Helmholtz resonator are decoupled. Thus, for example, in a wide operating range with regard to pressures and / or temperatures, the damping effect of the Helmholtz resonator in the region of the two resonance frequencies can be ensured.
  • Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
  • It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
  • Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.
  • Show, in each case schematically,
  • Fig. 1

    a diagram for the visualization of the frequency-dependent damping effect of a Helmholtz resonator.
  • Corresponding Fig. 1 can be connected to a conventional internal combustion engine 1 on the input side, a gas supply system 2 for supplying fresh air, so-called fresh air system 2 and the output side, a gas supply system 3 for carrying away exhaust gas, so-called exhaust system 3. The respective gas-conducting installation 2, 3 has in each case at least one gas-carrying line 4 or 5, wherein a Helmholtz resonator 6 or a silencer 7 can be connected to at least one of these lines 4, 5 and contains at least one such Helmholtz resonator 6 , In the example shown, both the fresh air system 2 is equipped with such a silencer 7 or such a Helmholtz resonator 6 and the exhaust system 3. It is clear that the respective line 4 and 5 and more than such a Helmholtz resonator 6 and may also contain more than one such silencer 7. Furthermore, it is also clear that the respective muffler 7 may also contain more than one such Helmholtz resonator 6.
  • According to the Fig. 1 to 5 such a Helmholtz resonator 6 comprises in each case a housing 8 which encloses a resonance volume 9, in particular gas-tight, and at least one neck 10 which connects the resonance volume 9 with a space, in this case with a line, namely with the fresh air line 4 or with the exhaust line 5, which conveys airborne sound. The Helmholtz resonator 6 serves to dampen the transported in the respective line 4, 5 airborne sound. It is important for the here in shunt arranged Helmholtz resonator 6 that its housing 8 closes the resonance volume 9 outside the respective neck 10 gas-tight to the outside.
  • According to the Fig. 2 to 5 the respective housing 8 has at least one oscillatable membrane 11 which forms a wall section of the housing 8 delimiting the resonance volume 9. With regard to its resonant frequency for oscillations which run perpendicular to the membrane plane in accordance with a double arrow 12, this membrane 11 is designed so that the first order of this resonant frequency corresponds to that resonant frequency of a structurally identical Helmholtz resonator which has no such membrane 11.
  • The effect of such a membrane 11 with the tuning according to the invention is with reference to Fig. 6 explained in more detail. In the diagram of Fig. 6 on the ordinate the acoustic attenuation is plotted in decibels dB, while on the abscissa the acoustic frequency is plotted in Hertz Hz. A dashed line is a damping curve 13 of a structurally identical Helmholtz resonator, which has no such membrane 11, applied. Visible this course 13 has a maximum 14 at a resonant frequency 15 of this membraneless, but otherwise identical Helmholtz resonator. This resonant frequency 15 of the membraneless Helmholtz resonator corresponds to the first order of the resonant frequency of the diaphragm 11. Furthermore, the diagram of the Fig. 6 a curve 16, the dependence of the attenuation of the frequency in the Helmholtz resonator 6 according to the invention with a such membrane 11 reproduces. As can be seen, the damping effect initially increases up to a first maximum 17, as a result of which the Helmholtz resonator 6 according to the invention has a first resonance frequency 18. After this first damping maximum 17, the damping effect drops to a minimum 19, which lies in the region of the resonance frequency 15 of the structurally identical but diaphragmless Helmholtz resonator, ie in the region of the resonance frequency of the diaphragm 11. Afterwards, the damping effect increases again up to a second maximum 20, at which the Helmholtz resonator 6 according to the invention has a second resonance frequency 21. Recognizable thus causes the specially designed membrane 11, that in contrast to a conventional membraneless Helmholtz resonator instead of a single resonant frequency 15, two resonant frequencies 18, 21 are present whose Dampfungsmaxima 17, 20 arranged approximately mirror symmetry to the resonant frequency 15 of the conventional membraneless Helmholtz resonator are.
  • The respective membrane 11 can in particular be produced integrally with the remaining housing 8, for example by injection molding of plastic. In this case, the membrane 11 differs from the rest of the housing 8 in particular by its thickness, which can be considerably reduced compared to the thickness of the remaining housing 8. The membrane 11 is designed so that it can vibrate, at least in the region of its connection to the surrounding housing 8, so that it can flex elastically in order to perform the desired oscillatory movements 12. In contrast, the rest of the housing 8 outside the membrane 11 is designed comparatively stiff. In particular, the housing 8 outside of the respective membrane 11 is designed so stiff that any resonant frequency of the housing 8 outside of the respective membrane 11 is at least ten times greater than the resonance frequency 15 of the identical, membraneless Helmholtz resonator with respect to their first order , In other words, if the housing 8 itself has a resonance frequency, its first order is at least ten times greater than the resonance frequencies 18, 21 of the Helmholtz resonator 6.
  • For the specific design of the resonant frequency of the membrane 11, which is to coincide with the resonant frequency 15 of the membraneless Helmholtz resonator, the membrane 11 may be designed in a suitable manner, so that they from the rest of the housing 8 in particular by the selected material, by the selected Thickness and if necessary by a profile as well as by their form differs.
  • In the examples shown, the respective housing 8 for the respective membrane 11 has a housing opening 22 which is closed by the respective membrane 11.
  • At the in Fig. 3 In the embodiment shown, the housing 8 has at least one cover 23. This is arranged on a side facing away from the resonant volume 9 outside of the housing 8, in such a way that it covers the membrane 11 forming or containing wall portion and in an additional volume 24, preferably gas-tight includes. By this construction, a certain decoupling of the damping effect of the membrane 11 from the ambient conditions, such as temperature and pressure, of the Helmholtz resonator 6 can be achieved. In addition, the lid 23 is preferably made less stiff than the housing 8 outside the membrane 11. Basically, an embodiment is possible in which the lid 23 is designed to be the same stiff as the housing 8 outside the membrane 11. Thus, the lid 23 may in particular be made of the same material as the rest of the housing. 8
  • At the in Fig. 4 shown embodiment, two membranes 11 and 11 'are shown purely by way of example. In principle, more than two membranes 11, 11 'can be provided. The two membranes 11, 11 'can be designed identically. Likewise, they can be tuned to the same resonant frequency with different design. Likewise, an embodiment is possible in which the two membranes 11, 11 'are tuned to different resonance frequencies. As a result, the attenuation maxima 17, 20 can be made wider.
  • At the in Fig. 5 shown embodiment, two necks 10 and 10 'are shown purely by way of example. In principle, more than two necks 10, 10 'may be provided. In the example shown, the two necks 10, 10 'are designed differently, such that the Helmholtz resonator 6 already has two different resonance frequencies due to the two necks 10, 10'. For example, the two necks 10, 10 'differ from one another by their cross section and / or by their length. In the example of Fig. 5 the housing 8 is also provided with two diaphragms 11 and 11 ', respectively, similar to the embodiment according to FIG Fig. 4 , Preferably, the two membranes 11, 11 'in the in Fig. 5 shown differently matched. Each of these membranes 11, 11 'is tuned to a different resonant frequency of a structurally identical Helmholtz resonator with the two different necks 10, 10' but without the membranes 11, 11 '. This ensures that the in Fig. 6 shown relationship for both "imaginary" resonant frequencies of the identical, membraneless Helmholtz resonator results. Accordingly, there are then a total of four resonance frequencies for the Helmholtz resonator 6 according to the invention with two different necks 10, 10 '.
