AMEE Vibrography

The AMEE Vibrography testing set powered by Chronos

The AMEE Vibrography system offers comprehensive tools for analyzing vibrations, providing advanced capabilities in displacement and strain mapping as well as modal and operational deflection shape (ODS) analysis. Utilizing Mercury RT® software, the system applies Digital Image Correlation (DIC) algorithms to track speckle patterns, ensuring sub-pixel accuracy in calculating displacement, strain, and deformation. Designed for frequency domain analysis, AMEE Vibrography is essential for vibro-diagnostic measurements, allowing for precise assessment of dynamic behavior in structures and components.
