SHOCK AND VIBRATION | TUNED MASS DAMPERS - 1

SHOCK AND VIBRATION | TUNED MASS DAMPERS TUNED MASS DAMPER (TMD) M-SERIES RESONANT DEVICE Moog’s advanced Magnetic-Series resonant devices are the perfect solution for structural resonance suppression and vibration control applications, and they are especially suited for precision micro-vibration applications. By replacing traditional elastomeric and fluidic damping technology with highly reliable rare earth magnetics, improved temperature range performance and a field-tunable damper coefficient has been achieved. The M-Series also facilitates rapid natural frequency adjustment, allowing the end-user to easily modify the device’s resonant frequency response. FEATURES • Highly efficient moving mass to parasitic mass ratio • Tunable resonant frequency via mechanical adjustment • Tunable damping ratio via a trimmer on devices • Convertible to an active reaction mass actuator (RMA) which can be useful for: – Structural dynamics testing with minimal mass loading – Active vibration damping or cancellation systems APPLICATIONS • Precision micro-vibration • Optical instruments • Machine tools • Product testing • Semiconductor fabrication equipment • Electron microscopes

TUNED MASS DAMPER M-SERIES RESONANT DEVICE MECHANICAL DIMENSIONS M-SERIES RESONANT DEVICE CONFIGURATIONS Configuration Tunable Voice Coil Damper The most popular and versatile configuration is an M-series device equipped with a tunable voice coil damper. Applications requiring a TMD or TVA (tuned vibration absorber) will benefit from the tunability of both frequency and damping of this passive device. Active Voice Coil This configuration can generally achieve the highest levels of vibration attenuation and give the user power to implement active damping. Fixed Damper This configuration can...
