Definitions
- the invention relates to active noise suppression for a noise-emitting Surface with at least one fast sensor connected to the surface and at least one that can be controlled by the signal of the fast sensor, actuator acting on the surface.
- Such a system for reducing the sound radiation from a flat surface is described, for example, by ME Johnson and SJ Elliott in Journal of Acoustic Society of America, 98 (4), Oct. 1995 under the title Active Control of Sound Radiation Using Volume Velocity Cancellation ".
- a fast sensor is used which, like the actuator, extends over the entire surface and only detects odd-numbered vibration modes, in particular the basic mode (1,1) and these vibrations by means of the actuator If the noise-radiating surface vibrates with higher vibration modes in which even one component is an even number, for example, (1,2), (2,3), etc. modes, such a surface-integrating sensor does not provide any Output signal more, since the integration over all oscillation peaks and valleys results in the sum signal 0.
- the invention uses axis-selective integrating fast sensors, which in the simplest case consist of strip-shaped Piezo foils are made. As soon as one along one axis such a sensor occupies a vibration mode with a odd component occurs, is the sum signal at this sensor no longer 0, so that an appropriately controlled actuator of this vibration mode can counteract.
- a plate 1 which can be, for example, a structural or body part and which are a source of interference 2, e.g. B. an internal combustion engine excited to vibrate is applied two piezoelectric foils 3 and 4 one above the other.
- the piezoelectric For example, slides 3 and 4 consist of stretched PVDF, which due to their manufacturing process is unidirectional piezoelectric Have properties.
- the two foils 3 and 4 are arranged one above the other that their preferred piezoelectric directions represented by arrows are oriented perpendicular to each other in the plate plane.
- the embodiment is thus the film 3 for deflections of the plate surface sensitive in the x direction and the film 4 for deflections in y direction.
- the voltage signals generated by the foils 3 and 4 are fed to a controller 5, which processes the signals according to known methods and controls an actuator 6.
- the actuator 6 can act on the plate 1 either in a punctiform or area-like manner and in such a way that vibration-induced deflections of the plate are counteracted.
- Feed Forward control, the vibration signals of the interference source 2 can be detected and fed to the controller.
- 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 of the left column supply the sum signal S 1y , those of the next column the sum signal S 2y etc.
- the row or column spacing of the measuring grid constructed from the acceleration sensors 32 must be adapted to the structure and to the frequency range in which noise reduction is desired. In order to resolve the highest possible mode orders, the distance d should be less than a quarter of the structure wavelength ⁇ of the highest mode.
- appropriately small-sized strain gauges, piezoceramics or piezofilms can also be used.
- each attachment element consists of a hard one Shell 42.1, which is provided with side walls 42.2, which in turn on the Place plate 41 and, together with 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 only be determined with difficulty.
- the vibrations and attachment elements the emitted 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.
