Design and Production of Application-Specific:

  • Conventional Constrained Layer Damping Systems Check it Out
  • Tuned Mass Dampers (TMD) / Tuned Vibration Absorbers (TVA) Check It Out



These systems are generally designed and developed in a very application-specific manner via careful consideration of the particular structural dynamics, operating temperature regime at the application site, as well as applicable outgassing, flammability, heat exposure, etc. requirements.

These systems can be configured to attenuate noise and vibration related to a wide range of vehicles and structures including:

  • Aircraft Fuselage Skin
  • Aircraft Wing Skin/Flap Structure
  • Aircraft Honeycomb Composite Panels
  • Aircraft Frames and Stringers
  • Satellite Structures
  • Launch Vehicle Payload Fairing Structures
  • Scientific Instruments
  • Automotive
  • Luxury Yachts
  • Marine
  • Heavy Truck
  • Consumer Products
  • etc.

General Background Information

Damping Technologies, Inc. was founded in 1989 in response to a need for unique vibration damping products which could efficiently deliver significant levels of damping to structures for control of high cycle fatigue and noise issues related to resonance response of aerospace structures. Damping Technologies, Inc.engineering assets have extensive experience with structural dynamics problem-solving in the aerospace, automotive, and consumer products industries.

The strength of the company resides with extensive knowledge and experience regarding viscoelastic damping materials. Damping Technologies, Inc. characterizes the dynamic mechanical properties of viscoelastic materials via ASTM E-756 Vibrating Beam Technique on a daily basis. Damping Technologies can select from a large menu of viscoelastic damping materials including, but not limited to, those that meet stringent out-gassing, thermal exposure, aging, and solvent exposure requirements.

Some engineering services companies perform damping system design, yet do no actual product manufacturing. In essence, they have absolutely no experience in the production/manufacturing environment. Damping Technologies, on the other hand, is a full service damping solution resource having both engineering and manufacturing expertise relative to structural dynamics solutions. There is no substitute for experience, and there is no substitute for manufacturing experience when designing something which must ultimately be manufactured. It can absolutely mean the difference between success and failure. This is one reason that damping solutions are not more numerous than they are. Damping solutions are very difficult to bring to the production environment. There are many fine details which must be addressed and controlled to bring high performance application-specific damping products to full production.

To summarize, what is required for solution and optimization of damping solutions for challenging noise/vibration control applications is a solid blend of hands-on structural dynamics engineering experience, manufacturing experience, as well as innovation derived from years of working with viscoelastic materials and application-specific damping systems.

When we talk innovation, we aren't just talking about damping system design. We're talking analysis, design, component material selection, processing, production, and quality control. We regard our business as a full-service approach to structural dynamics solutions.
