Solutions for Damping

Trelleborg Damping Solutions is leading the way in the production and development of noise and vibration damping solutions for a wide range of applications in many industries.

Let us be your partner to develop and optimize existing and future e-mobility solutions!

Applied Damping Material

ADM - is a Constrained Layer Damping (CLD) material based on metal layers vulcanized together with rubber to produce a strong and durable laminate. This provides superior damping of structure-borne noise and can be cut and formed to fit most surfaces. Typical applications are cast engine covers such as inverter covers, valve covers, chain covers and oil pans.

ADM
Pressed vulcanized steel and rubber for robust design, ADM can be formed and cut to part using conventional press operations such as press forming, deep-drawing and die cutting. We use these materials to produce made-to-measure customer specific components.

Applications

Housings and covers where damping is needed:
  • Power electronic units
  • Engine covers & oil pans
  • Cast covers such as valve covers, chain covers
  • Flex plates
  • Supercharger/intercooler
  • Start/stop system
  • Transmissions/flywheel
Benefits
  • Reduces structural vibrations and radiated noise
  • Formable to various shapes
  • Damping where it matters

Applied Damping Foam - ADF 

ADF is a constrained damping material is made of metal and viscoelastic material (VEM) combined with a layer of closed cell foam. Designed to reduce structural-borne noise by combining damping and isolation.

ADF

Provides superior damping of structure-borne noise of complex 3D surfaces. It combines the functions of damping and isolation tuned to minimize radiation from vibrating surfaces. ADF is especially suitable for stiff structures such as cast iron- or aluminum structures.

Applications

Housings and covers where damping and isolation is needed:

  • Gearbox housings, transmissions
  • Engine covers
  • Super chargers
  • Oil pans
  • Electrical motors

Benefits

  • Vulcanized metal and rubber for robust design
  • Can be used on complex surfaces
  • Formable to various shapes
  • Reduces both resonant vibrations and forced excited vibrations
 

Visco-LAM

Visco-LAM is a sandwich material made of two layers of sheet metal laminated together with an intermediate layer of viscoelastic polymer. Various types of metals and alloys can be used, in different thicknesses, with surface treatment if needed. The material performance can also be optimized by changing the dynamic properties of the polymer.

Visco-LAM

Visco-Lam is typically used for replacing existing resonant components.

Applications

  • Dash panels, floor and roof panels
  • Electronic covers, engine covers, valve covers oil pans
  • End covers/access covers, transmission/gearbox covers
  • Wheelhouse, consoles/brackets
  • White goods
  • Dual wall concepts, acoustic enclosures
Benefits
  • Improved NVH without adding components
  • No added mass when replacing existing part
  • Weldable options available
  • The material combination can be optimized for the specific application

Duru-LAM

Duru-LAM is an excellent choice where a strong and robust material is needed for sound and vibration damping. Duru-Lam is a sandwich material made of two layers of sheet metal vulcanized together with an intermediate layer of elastomer. Various types of metals and alloys can be used, in different thicknesses, with surface treatment if needed.

Duru-LAM

Stands for durability, rubber and laminate. Duru-Lam is used in demanding environments where media resistance and mechanical properties are of high importance. 

Applications

  • Replacing existing resonant components, for example:
  • Baffle plates, splash shields
  • Brackets/consoles
  • Motor mounts
Benefits
  • Improved NVH without adding components
  • Superior durability
  • Can be used inside engines/transmissions 

Rub-LAM

Rub-LAM is an excellent choice of material for sealing, isolation, friction as well as sound and vibration damping. Various types of metals and alloys can be used, with surface treatment if needed. The choise of elastomer and thickness is based on the requirements of the application.

Rub-LAM

Rub-LAM is an elastomer to metal sandwich material where the elastomer is vulcanized on one or two sides of the metal layer.

Applications
  • Washers, seals/gaskets
  • Radial dampers for gear wheels and pullys
  • Steering systems
  • Cealings, flooring
Benefits
  • Improved NVH
  • Durable in stamping and forming
  • Sealing properties
  • Various friction levels available
