Vibration

Vibration testing is used to determine the response of a test specimen to mechanical excitation encountered in it's shipping or operational environment. Vibration testing can also precipitate manufacturing or latent defects in products or components.
American Environments Company generates vibration environments utilizing either Dynamic, Hydraulic or Mechanical vibration systems.
AECO provides full service vibration testing. We control, measure and analyze vibration events.
