Absorbing vibrations and damping noise created during vehicle operation makes driving a more comfortable experience. Trelleborg Damping Solutions is an expert in eliminating unnecessary and unwanted vibrations through advanced material formulation and innovative laminate technologies. -By Jan Sklucki

Trelleborg Damping Solutions

Damping engineers are available to help select the right products to minimize and eliminate problem vibrations. Whether advanced materials, surface treatments or laminated
composites, Trelleborg offers unique and customizable solutions to solve customers’ most difficult engineering challenges.

 

REPLACING RESONANT COMPONENTS OR CREATING NEW VIBRATION RESISTANT PRODUCTS
Trelleborg Damping Solutions laminates can replace existing resonant components, such as mounts, brackets, washers and covers. They reduce Noise, Vibration and Harshness (NVH) where it matters most without adding mass, offering robust and complex-shaped design options..

 

  1. Visco-LAM 
    Visco-LAM is an advanced laminate material with an intermediate layer of customizable viscoelastic polymer. By modifying the properties of the polymer and choosing the right metals and alloys, the solution can be tailored to the application.
  2. Duru-LAM 
    When a strong and robust material is required, Duru-LAM offers increased media resistance and improved mechanical properties. A range of thicknesses of different metals can be used around an interior layer of elastomer, providing the strength and performance needed to operate effectively within engines and transmissions.
  3. Rub-LAM
    To add sealing properties, components can be formed from two elastomer layers around a metal interior layer. Rub-LAM permits radial dampers, washers, seals and gaskets to be formed with improved noise reduction and damping.

     

    MINIMIZING VIBRATIONS IN EXISTING COMPONENTS
    When components can’t be replaced, they can be modified with applied solutions to reduce or isolate vibrations.

  4. Applied Damping Material (ADM)
    A constrained layered damping material composed of layers of metal and rubber vulcanized together to form a strong and durable laminate that effectively reduces  structural vibrations and radiated noise. It can be cut and formed to fit to most surfaces and shapes using conventional press operations, such as press forming, deep-drawing and die cutting.
  5. Applied Damping Foam (ADF)
    Metal and viscoelastic material are combined with a layer of closed cell foam to combine damping and isolation in a single material. Especially suited for use on stiff structures, such as cast iron or aluminum components, minimizing the radiation from vibrating surfaces

Covers to protect electronic

Covers to protect electronic components are frequently sources of resonant vibration. To solve this, Visco-LAM or Duro-LAM materials are shaped using a special laminated process to form a new replacement cover that improves performance without adding mass. If replacement is not possible, ADF or ADM can be applied to existing covers or the housing to give effective damping.
ELECTRIC DRIVES AND MOTORS, HVAC AND PUMPS

Applied Damping Material

Applied Damping Material (ADM) is applied to surfaces that radiate excessive noise, providing superior damping and reducing vibrations. If isolation is also required, Applied Damping Foam (ADF) combines damping and isolation to reduce structure-borne noise.
GEARBOX, GEAR WHEELS

GearBox

A radial damper combines damping materials with metal gear wheels, reducing tonal and whining noises generated during operation. Many vibrations within the system can be reduced by intercepting the vibration path between different components within the engine assembly.
