Definitions

  • the invention relates to a device and a method for reducing a vibration of a particular transparent plate, in particular a disc, taken in the measurement data from the edge region of the vibrating plate and the plate is loaded over its edge region with a compensation oscillation in response to these measurement data such that thus a At least partial reduction of the vibration of the plate occurs.
  • a method for vibration compensation of beams is known from the prior art, in which a modal filtering a separation of the Sensor signals in shares of each vibration modes is performed.
  • Such a method is also known by the technical term method of independent modal space control ("IMSC: Independent Modal Space Control").
  • IMSC Independent Modal Space Control
  • This separation of components can be created by a linear combination of two sensor signals, but these sensor signals must be suitable for this, or the sensor signals or measurement data must be taken from suitable locations on the structure.
  • sensors are arranged distributed over the beam structure.
  • the invention is therefore based on the object to improve a method for vibration compensation of a particular transparent plate of the type described in such a way that on the one hand steadfast allows a comparatively high extinction of plate vibrations, on the other hand, however, a low process cost, which does not affect the plate, especially their field of vision requires.
  • the invention solves this problem by measuring data taken at locations of the edge region with maximum curvature of vibration modes of the plate, by linear combination suitable measurement data parameters for at least one vibration mode, in particular at least two vibration modes of the plate determined, depending on these parameters for each quadrant the plate vibration components are calculated on the compensation vibration and thus each relevant quadrant of the plate is charged to the common formation of the compensation vibration.
  • a plate can be understood as a plate-shaped substrate.
  • each relevant quadrant of the plate can then be loaded in order to jointly form the compensation oscillation.
  • the invention can therefore stand out from the prior art despite reduced process complexity by a faster, stable and more efficient vibration damping, preferably if this at least two modes of vibration are compensated, for which purpose no visual impairment of the transparency of the plate must be taken into account.
  • the method for vibration compensation can be improved, because a more even total load of the quadrants can thus be exploited on account of several points of the plate loaded in parallel.
  • the method can be improved if no vibration components are applied to the plate at the points for taking measurement data. Adverse effects of overlays can thus be avoided, which also the stability of the process can be improved.
  • vibration compensation of these modes can be made possible in a quick and simple manner.
  • the dynamics as well as the stability of the method can thus be increased, in particular if in this case the first three vibration modes are taken into account.
  • the invention achieves the stated object in that sensors are provided in the edge region at locations with maximum curvature of vibration modes and that the control device both at least one modal filter connected to the sensors, in particular at least two modal filters connected to the sensors, for separating the measurement data in Shares of individual vibration modes of the plate, as well as for each filter associated therewith or with each filter controller for generating controlled variables as a function of the separated portions of the measured data and each associated with at least one actuator of a quadrant switching stages for joining the controlled variables to vibrational components of the compensation oscillation as a function of the quadrant-wise control of the actuators.
  • the control device has both at least one modal filter connected to the sensors, in particular at least two modal filters connected to the sensors, for separating the measured data into parts of individual vibration modes of the plate, as well as for each filter an associated controller for generating controlled variables depending on the separated portions of the measured data.
  • Increased force introduction into the plate can be made possible if in each quadrant of the plate an actuator group of parallel and distributed actuators is provided. In addition, it can be used to create a more uniform force input than with a punctual load on the plate.
  • the influences of the decisive eigenmodes of the plate can be detected and compensated, if in each case between two quadrants at least one sensor is provided.
  • the risk of feedback between sensors and actuators can be significantly reduced, which can increase the stability of the device, especially when the sensors are provided on the opposite side of the plate actuators.
  • control device has three modal filters connected to the sensors for vibration compensation of the first three vibration modes of the plate, then it has surprisingly been found that those modes can be reduced which have a decisive influence on a plate vibration. A particularly high efficiency in the vibration compensation can be achieved.
  • the modal filters have adders and / or subtractors connected to the sensors.
  • a fast and stable device for vibration compensation via, for example, simple downstream proportional elements can be made possible via the parameters of the amplitude.
  • the Modalraumregelung can be simplified if the measured data recording in the edge region of the plate with maximum curvature of vibration modes of the plate takes place.
  • the modal space control can determine parameters for at least one oscillation mode, in particular at least two oscillation modes, of the plate by linear combination of suitable measured data and depending on this For each quadrant of the plate, this parameter calculates vibration components on the compensation oscillation.
  • the use of at least two modes of vibration has been found to be preferable for more efficient vibration compensation.
  • Modes that essentially shape the plate oscillation can be reduced especially if measured data is recorded between two quadrants and the modal space control uses its linear combination to calculate parameters for at least the first three oscillation modes of the plate.
  • a highly dynamic vibration compensation can result if the modal space control using the linear combination determines the amplitudes (32, 33, 34) of the particular first three vibration modes (M1, M2, M3)
  • FIG. 1 illustrated embodiment shows a device 1 for vibration compensation with a plate 2, which is mounted at their ends, for example via a clamping, not shown in a frame.
  • a clamping not shown in a frame.

  • the plate 2 is capable of oscillating, which among other things also allows undesirable vibrations.
  • actuators 3, 3 ', 3 ", 3'" are provided on the plate 2 in the edge region 4 in order not to reduce the transparency of the plate 2 and / or a central weight load to avoid the plate 2.
  • the vibration of the plate 2 to be compensated becomes Measured via sensors 5, 5 ', 5 “, 5'", whereby measurement data 6, 6 ', 6 ", 6'” are recorded by this measurement.
  • the sensors 5, 5 ', 5 “, 5'” are also provided on the plate 2 in the edge region 4 thereof for the above reasons, preferably on the side opposite the actuators 3, 3 ', 3 ", 3'", which is on the dash-dotted representation of the sensors 5, 5 ', 5 “, 5'” can be seen in the figures.

  • 3 modal filters 9, 10, 11 a vibration compensation of the first three vibration modes M1, M2, M3 of the plate 2 can be made possible.
  • the switching stages 19, 20, 21, 22 therefore add the controlled variables 12 ', 13', 14 'to oscillation components 15', 16 ', 17' and 18 'to the compensation oscillation as a function of the quadrant-wise actuation of the actuators 3, 3', 3 ", 3 '" together.
