Definitions

  • the invention relates to an arrangement for damping vibrations on structures or components, consisting of a damper mass which is connected to the structure or component via resilient and vibration-damping elements.
  • the known dynamic vibration dampers consist of a damper mass that oscillates or via a vibration element, e.g. an axially loaded rubber element is attached to the structure or component and its oscillating or oscillating movement through special damping elements, e.g. in the manner of motor vehicle vibration dampers (DE-OS 27 18 962) or with wire rope coil springs (DE-PS 28 06 757) is damped.
  • a vibration element e.g. an axially loaded rubber element is attached to the structure or component and its oscillating or oscillating movement through special damping elements, e.g. in the manner of motor vehicle vibration dampers (DE-OS 27 18 962) or with wire rope coil springs (DE-PS 28 06 757) is damped.
  • vibration dampers that are largely wear-free and low-maintenance and have clearly defined non-linear characteristics, so that a clear calculation is possible.
  • a vibration-damping arrangement is desirable, the natural frequency of which can be varied over one and the same element over a larger frequency range.
  • the invention is therefore based on the object of making an arrangement of the generic type in such a way that the abovementioned favorable properties are achieved.
  • friction spring elements are provided as resilient and vibration-damping elements, which are arranged radially, tangentially and / or perpendicular to the direction of the vibrations to be damped on the structure or component.
  • a pendulum suspension of the damper mass is selected with pendulum rods or angle levers, which allows any arrangement of the friction spring elements. This results in a wide range of the adjustable natural frequency of the vibration damper and a large variation in the design. Furthermore, the susceptibility to faults and the need for maintenance is very low.
  • the suspension and damping properties of the friction spring elements can be adjusted by the type, number and preload of the ring elements. Furthermore, a large non-linearity of the friction spring element can be achieved through the free choice of the preload. As a result, a larger frequency range can be covered when the element is set.
  • the structure or component equipped with a vibration damper according to the invention is primarily designed so that the damper mass is suspended on pendulum rods and the damper mass is supported on the ring spring elements via the rods.
  • Another embodiment is the suspension on angle levers, which are articulated.
  • the damper mass is supported indirectly via the friction spring elements.
  • the reaction to the structure is transmitted through the upper suspension.
  • a stepless change in the lever arms can be achieved by the arrangement of the friction spring elements and a stepless power transmission can be achieved by changing the inclination of the elements to the lever. This range of variation has a great advantage. If previous calculations for the structure or component are incorrect due to incorrect information, particularly with regard to the relevant natural frequencies and the reduced dynamic replacement masses, or if changes have occurred to the structure, the vibration damper must be adjusted to the new design values without any particular effort.
  • the dynamic vibration dampers according to the invention can be inside or outside of a building 1, e.g. Antenna support, chimney or mast can be attached.
  • Brackets 6, to which pendulum rods 4 or angle levers 4a are articulated, are fastened to the structure 1 diametrically opposite one another.
  • These pendulum rods 4 or angle levers 4a take up the weight of the damper mass 2, which can have the shape of a closed or open circular ring or polygonal ring, for example.
  • Both resilient and damping friction spring elements 3 are arranged between the pendulum rods 4 or the angle levers 4a and the structure 1. These elements 3 can engage at any point on the pendulum rods 4 or the angle lever 4a and on the building-side fastening strips 5. They are connected by suitable articulated connections 7, for example ball joints with fork heads and bolts, to the pendulum rods 4 or the angle levers 4a and the coupling strips 5.
  • the friction spring elements 3 have a damping in their ring elements due to the friction and an adjustable, precisely determinable spring characteristic due to the composition (type, number) and the preload. It is also advantageous that the resilient and damping properties of the friction spring element 3 are independent of the oscillation speed, oscillation frequency and temperature.
  • the elements 3 are also corrosion-resistant and practically maintenance-free. Due to the shape of the arrangement, they take up little space. Due to the very variable arrangement of the friction spring elements 3, a damper design can be tuned to any natural frequency within the framework of the specified geometry, i.e. a change in the natural damper frequency is possible at any time.
  • the friction spring element 3 is essentially formed from outer rings 3a and axially slotted inner rings 3b, which interact via conical contact surfaces and are arranged within a housing 3c, 3d.
  • the housing has a fastening eye 3e at the ends of its two telescoping housing parts 3c and 3d.
  • a central screw 3f is used to adjust the preload of the friction spring element 3.
  • the friction spring element 3 can also be stressed by suitable articulation in the pulling and pushing directions.
  • a modification, not shown, for example FIGS. 1 and 2 may consist in replacing some friction spring elements 3 by articulated, rigid connecting parts. Deviating from the exemplary embodiments shown, it is also entirely possible to arrange friction spring elements 3 radially between the structure 1 and the damper mass 2. Combinations of radial, tangential and vertical arrangements of friction spring elements 3; For example, in addition to the friction spring elements 3 lying tangentially in FIGS. 1 and 2 or to the friction spring elements 3 standing vertically according to FIG. 3, friction spring elements 3 can also be arranged radially.
