Definitions

  • the invention relates to a device for active noise cancellation Noise-radiating surface according to the preamble of patent claim 1.
  • U.S. Patent No. 5,415,522 shows active noise control with sound sources to generate a secondary field.
  • a noise-radiating element held by clips over an inner wall section.
  • the object of the present invention is therefore a device for active noise suppression to create, by means of which vibration modes with at least an odd-numbered component can be detected and suppressed.
  • a plate 1 for example can be a structural or body part and which is caused by a source of interference 2, e.g. an internal combustion engine that is excited to vibrate, two piezoelectric Slides 3 and 4 applied one above the other.
  • the piezoelectric foils 3 and 4 consist for example of stretched PVDF, which due to their manufacturing process have unidirectional piezoelectric properties.
  • the two Slides 3 and 4 are arranged one above the other so that their are represented by arrows preferred piezoelectric directions in the plate plane perpendicular to each other are oriented.
  • the film 3 is thus for Deflections of the plate surface in the x direction are sensitive and the film 4 for Deflections in the y direction.
  • the voltage signals generated by the foils 3 and 4 are a controller 5 supplied, which processes the signals according to known methods and an actuator 6 controls.
  • the actuator 6 can either point or area on the Plate 1 act in such a way that vibration-related deflections of the Plate is counteracted. For a so-called "feed forward" regulation the vibration signals from the interference source 2 are also detected and fed to the controller become.
  • the speed of a plate 31 is detected point by point by means of individual sensors 32, which are distributed in a matrix over the surface of the plate 31.
  • acceleration sensors which are glued to the surface of the plate 31 and which are electrically connected to one another in rows and columns are suitable.
  • the sensors in the upper line then deliver, for example, a first sum signal S 1x , those in the second line the signal S 2x and so on;
  • the sensors in the left column supply the sum signal S 1y , those in the next column the sum signal S 2y etc.
  • each attachment element consists of a hard one Shell 42.1, which is provided with side walls 42.2, which in turn on the Rest plate 41 and, together with the shell 42.1, a cavity 43 form.
  • the shell 42.1 is in accordance with the exemplary embodiments 1, 2 or 3 are equipped with axis-selective fast sensors 44 and 45, whose signals are fed to a controller 46. This controls an actuator 47, which acts centrally on the shell 42.1.
  • Such attachment elements are particularly suitable for noise suppression of complex sound-emitting structures in which the vibration and radiation behavior can be determined only with difficulty.
  • the vibrations and attachment elements the radiated sound of the actually vibrating structure (plate 41) in turn stimulated.
  • the active system integrated in the front elements reduces their noise radiation and thus the sound radiation of the structure self.
