forces in motion

MAURER Tuned Mass Dampers (TMD) are designed as spring-mass or pendulum systems. The spring stiffness of the secondary mass is chosen in such a manner that an optimal tuning of the main system is achieved. A commonly viscous damping element dampens vertical, horizontal or torsional vibrations. The damping element can also be filled with a magneto-rheological fluid to enable continuous control. For small-sized mass pendulums up to approx. 300 kg, MAURER also offers friction dampers whereby the damping force is realized via friction plates.

Benefits of MAURER TMDs

• The different mass damper types guarantee the best possible solution to the vibration problem.
• Optimal design of all mass damper types as a service by MAURER.
• Vibration measurement on the structure by MAURER.
• Quality assurance by measurement of the dynamic properties of the mass dampers in the workshop and on the structure.
• All MAURER TMDs are robust, maintenance-free and long-living (>20 years) thanks to optimal design, precise production and quality control.

Specific benefits of MAURER TMDs

• standardTMDs: cost efficient

• foldedTMDs & compactTMDs:
  • significant cost reduction in high-rise buildings due to minimised height of these TMD types
  • optimal frequency tuning in both main directions due to innovative cable fixation tunings
• controlledTMDs:
  • maximum comfort in buildings through improved vibration reduction of up to 80% compared to passive TMDs same vibration reduction as with passive TMDs but with reduced tuned mass (75% to 85% of nominal tuned mass)
  • reduction of the damper mass by 30% for vibration reduction equaling that achieved by passive mass dampers
  • integrated monitoring of structural vibrations

MAURER offers the optimal TMD with a tuned mass up to 1,000 t for any vibration problem.
