• Less noise and vibration with foam
  by both absorbing sound and damping vibration. Viscoelastic damping materials applied directly to the surface of the vibrating structure absorb and distribute vibration or shock while helping reduce any noise present. Damping materials, about 1/8-in. thick, can substantially reduce structure...
• Structural Dynamics and Vibration in Practice: An Engineering Handbook
  Structural Dynamics and Vibration in Practice: An Engineering Handbook. Introducing the theoretical, testing and control aspects of structural dynamics and vibration, this straightforward text, primer and reference opens up the dynamic behavior of structures and provides an understanding of key...
• An Integrated Approach to the Dynamic Testing of Aerospace Structures
  identification techniques, which allows to do a very detailed analysis of the flight results resulting in the frequency, damping and modeshapes of the structure during the flight Vibration Qualification Tests (Vibration Control)The SCADAS III front-end is also perfectly suited for the vibration qualification...
• Shake, rattle, and modal analysis
  with twist. The first five modes of vibration for the cup holder range from 15.7 to 144 Hz. Mention FEA and the first things that comes to an engineer's mind are stress and deflection. But FEA can do more than that. It can also show how structures shake when they vibrate, a topic that gets a lot...
• Where Reticulated Polyurethane Foam's a Fit
  material is strong enough to handle industrial applications ranging from sound and vibration absorption to sparkproofing fuel tanks in aircraft and race cars. The flexible foams feature an open-pore structure with pore sizes and densities engineered specifically to suppress explosions and mitigate...
• Optical Metrology for Large Telescope Optics
  design specifications. More recently, "dynamic interferometry" has been implemented for vibration-insensitive measurement of large optics. The data is used to control polishing operations, verify dimensional stability of support structures, align mirror segments and complete other critical...
• Pressure-Sensitive Adhesives Make Strong Joints at Low Cost
  The Adhesive Advantage: Strong Joints, Low Costs Pressure-sensitive adhesives minimize vibration, noise, and corrosion, making them a viable and cost-effective alternative to mechanical fasteners. Pressure-sensitive adhesives use less material and reduce assembly costs, compared to mechanical...

  by applying airflow and temperature control within the machine chamber and through the use of a hybrid active damper. The tool's improved vibration isolation structure allows synchronization control at a high scanning speed. A series of in-process monitors detects and measures ESD events accurately...

  centering wafer holder. The instrument is equipped with PreFIX, which enables the fast and flexible exchange of diffractometers, including optical modules indispensable for advanced materials research. PreFIX eliminates the need for realignment when switching from one kind of analysis method to another...
