  • Patent number: 10309469
    Abstract: A friction damping cast component and method of production are disclosed. The components may be rotary, such as a cast brake rotor, or may be non-rotary, such as a cast suspension part or a cast engine block. Regardless of the type of component, a two-part vibration-damping insert having a thin metal core and a thin metal sheath is provided. The sheath fully encompasses the core in such a way that a dry sliding friction contact develops at their interfaces. The outer surface of the sheath with the metal core inside is rigidly bonded to the cast material that surrounds it during the casting process. The sheath surfaces may have a number of openings that allow a limited infiltration of molten cast iron material just inside the immediate vicinity of the sheath openings for spot rigid bonding between the surrounding cast material and the insert surfaces during casting.

  • Patent number: 10253836
    Abstract: The present invention is directed to three dimensional weaves composed of wires or yarns that offer the potential for damping not achievable with solid materials, including high temperature damping. Three damping mechanisms have been identified: (1) Internal material damping, (2) Frictional energy dissipation (Coulomb damping), and (3) inertial damping (tuned mass damping). These three damping mechanisms can be optimized by modifying the wire material chemistries (metals, ceramics, polymers, etc.), wire sizes, wire shapes, wire coatings, wire bonding, and wire architecture (by removing certain wires). These have the effect of modifying the lattice and wire stiffnesses, masses, coefficients of friction, and internal material damping. Different materials can be used at different locations in the woven lattice. These design variables can also be modified to tailor mechanical stiffness and strength of the lattice, in addition to damping.

  • Patent number: 9567192
    Abstract: An oscillation damper for vibration drivers for suspension from a load-bearing means displays a damping body connected on its opposite end faces to pressure bodies which are variable in their spacing, having a rigid support element which is assigned to the load-bearing means and a rigid support element which is assigned to the vibration driver. The two support elements are connected in an articulated manner by way of flexible ties to each pressure body. The longitudinal axes of the ties form in each case an acute angle with the vertical that decreases as tensile force increases, on account of which high tensile forces can be introduced onto the damping body. Simultaneously with the churning operation of the damping body a pendulum movement of the laterally disposed pressure bodies about the articulations of the ties takes place, on account of which vertical oscillation is largely eliminated.

    Abstract: Device for three-dimensional vibration insulation between structures or industrial equipment in general and the foundations thereof, comprising a hexagonal framework formed by six plates connected so as to pivot in relation to each other by horizontal parallel hinges, at least a spring and a damper being arranged between the plates. The device further comprises a connector arranged its series on the upper plate so as to pivot about a horizontal axis perpendicular to the axis of the hinges. The insulating system comprises a plurality of devices operating in parallel and oriented in such a way that the transverse axes thereof (defined by the hinges) converge onto a vertical axis that contains the centre of gravity of the structure or equipment being insulated, in particular against high-intensity seismic activity with large displacements.

  • Publication number: 20150034797
    Abstract: A system for managing noise and vibration in a vehicle includes a housing defining an internal cavity. A compliant member is attached to the housing and further defines the internal cavity. A magnet is operatively fixed to the housing in the cavity and has a magnetic field. A coil is positioned in the cavity and is configured so that there is relative movement between the coil and the magnet in the magnetic field in response to movement of the compliant member relative to the housing. A resistor is in electrical communication with the coil to form an electrical circuit. Relative movement of the coil in the magnetic field induces a current in the circuit that creates an opposing magnetic field, thereby reducing transmitted dynamic forces.

  • Patent number: 8935892
    Abstract: A building includes a connection between an engineered wood load bearing element of the building such as a column, beam, or load bearing panel, and another load bearing element or a foundation of the building. At least one tendon ties the load bearing elements or the load bearing element and the foundation together. One or more energy dissipaters, replaceably connected between the load bearing element and/or the foundation, absorb energy when a loading event causes relative movement of the connection. The engineered wood element may be a laminated veneer lumber element, a parallel strand lumber element, or a glue laminated timber element, for example. Typically all of the load bearing elements of the building will be engineered wood elements. The building may be single or multi-storey. The building system enables lightweight low cost buildings, with energy dissipaters which may be replaced after extreme loading. The building may be prefabricated.

  • Publication number: 20140326850
    Abstract: An anti-vibration unit, which enables a reduction in man-hours to be achieved during manufacturing and a reduction in the number of parts, is provided. A boss member of an anti-vibration device is pressed into a press-fitting section of a second bracket so as to be firmly fixed. The omission of the bolt enables a corresponding reduction in the number of parts. Moreover, by omitting the bolt in this way, there is no need to form a female threaded section on the boss member of the anti-vibration device, thus enabling a corresponding reduction in man-hours during manufacturing. In addition, when chemically treating the boss member of the anti-vibration device, it is unnecessary to implement a step for protecting the female threaded section with a masking bolt, thus eliminating the need to attach and detach the masking bolt, which in turn enables a corresponding reduction in man-hours during manufacturing.
