Damping and Isolation Material Technology
• Core technology: design with elastomers and viscoelastic materials (VEMs)
– VEM tester: material tests over –55°C to +150 °C, 2-200 Hz
– Large database for special requirements
• Integration with finite element models• Developed elastomeric material with almost constant
properties over wide temperature range• Thermally conductive isolators

Tuned Mass Dampers
CAV May 2012
Tuned Mass Dampers
SOLUTION: Tuned Mass Dampers (TMDs)
• New lightweight large-windowed cars exhibit higher levels of vibration during operation
• Structural resonances at lower frequencies• Problems emerged after much of design and
construction was complete• ISO Std 2631 on Human Exposure to Whole-
Body Vibration (health, comfort, perception)• Lateral vibration – one key mode• Emphasis on 10 Hz and 12.5 Hz third-octave
bands when running at high speeds
• Engineering and test program• Finite element analysis• Design/test of prototype units• Installation and running tests in railcars
• Production and delivery• 4 TMDs per car installed in over 200 cars• Typical in-service reduction of 50%

Isolation “SoftRide”
• Whole-spacecraft vibration/shock isolation system results in reduced loads for spacecraft components
– Less design time– Less test time– Less mass dedicated to launch survival– More mass dedicated to on-orbit
performance
