摘要： Known drive circuits for vibration conveyors control the supplied power by means of a variable transformer or phase control regulation. The conveyors are mechanically tuned to the mains frequency or double the mains frequency. Disadvantages of this are e.g., that the mechanical tuning must be performed regularly while pausing the conveyor. According to the invention current and voltage are measured continuously, and basic relations permit the length of the airgap to be calculated based on these measurements. The result is used in a control loop which maintains sinusoidal supply of power at the relevant mechanical resonance frequence, which hence does not need to be adjusted periodically.

摘要： Beim Betrieb eines Resonanzschwingungssystems mit zwei gegeneinander schwingenden Massen ist ein Aufeinanderschlagen der Massen durch eine Regelung zu verhindern. Insbesondere bei Verwendung eines Magnetantriebs wird zusätzlich angestrebt, den Luftspalt möglichst klein zu halten.
Zusätzliche Schwierigkeiten treten auf, wenn eine der Hauptmassen während des Betriebs (beispielsweise durch Zuladung von Fördergut) ihr Gewicht in unvorhersehbare Weise ändert. Erfindungsgemäß wird eine "ablösende Regelung" vorgeschlagen, bei der ab einem vorgebbaren Wert für Gesamtschwingbreitenregelung erfolgt.
Dazu ist einem einzelnen Regler (9) eine Vergleichseinrichtung (12) vorgeschaltet, die nur einen (gewichteten) Maximalwert von jeweils zwei erfassten Istgrößen für den Vergleich mit einem vorgegebenen Sollwert (w) weiterleitet.

摘要： A control method and a controller of a vibrating feeder which allow the vibrating feeder to have an excellent responsibility at the time of start thereof and to suppress the mechanical strength of the vibrating feeder by readily smoothing overshoots which might otherwise be caused by a transient response at the time of start are provided. A feed-power is set at a level corresponding around to or higher than a target amplitude of the vibrating feeder 1 at the time of start thereof, so that it has the excellent responsibility at the time of start. Further, following to that, it is set at a level lower than that at least once, so that the overshoot at which the vibrating feeder 1 exceeds the target amplitude may be suppressed, thus allowing to reduce the mechanical strength of the vibrating feeder.

摘要： A vibration control device for structures, which constitutes a double action vibration absorber of positive control type by providing a driving member of a predetermined mass mb as a second added mass body relative to a first added mass body of a predetermined mass ma, in which the first added mass body is provided on the structure via a support comprising a plurality of high damping laminated rubber pieces, whereby a downward arc-like running surface (4) is formed on which the second added mass body is to be run. The weight of the first added mass body is set to 1/500 to 1/1000 of the total weight of the structure to be vibration controlled, and the weight of the second added mass body to 1/20 to 1/100 of the weight of the first added mass body. A great damping factor ha of 10 to 50 % is set for the support, and the angular frequency omega a of the first added mass body and the angular frequency omega b due to the free vibration of the second added mass body on the arc-like running surface are synchronized with the natural circular frequency omega 1, whereby a control force corresponding to the response of the structure is imparted to the driving member as a second added mass body, thereby reducing the response by the structure to earthquake or wind.
