Vibration Testing

A key aspect of vibration testing is the machine table and the fixture that supports the component. Both need to be stiff, strong, lightweight and have good damping characteristic to reduce resonance. Magnesium AZ31B-Tool Plate (TP) is an ideal material for these due to its combined physical and mechanical properties.

Damping capacity is a measure of a material’s ability to dissipate elastic strain energy during mechanical vibration or wave propagation. When ranked according to damping capacity, materials may be roughly categorized as either high or low damping. Low damping materials may be utilized in musical instruments where sustained mechanical vibration and acoustic wave propagation is desired. Conversely, high damping materials are valuable in suppressing vibrations for the control of noise and for the stability of sensitive systems and instruments.

Magnesium Plate Benefits:

  • Best damping capacity of any metal
  • Lightweight material accommodates heavier loads
  • Allows for higher resonant frequencies over aluminum
  • Energy Savings
