Reliable Evaluation of Damping Materials and Composites

Carrousel measures the dynamic vibration properties of coated or non-coated materials. The method is based on the classic “Oberst” procedure where Autoneum has improved both the measurement procedure itself and the mathematical model used to evaluate the results. The Carrousel software automatically calculates the damping loss factor at various conditions and temperatures as well as controlling both the Carrousel apparatus and the all-important temperature when measuring in a temperature chamber.

Carrousel is available in two versions:

  • Carrousel with a 20-sample holder
  • Carrousel SSH (single sample holder)

Carrousel offers:

  • Support with the development of components for noise damping and the comparison of different products
  • User-friendly and high-performance software for controlling the entire measurement procedure including measurement set-up, measurement sequence and evaluation of results
  • Shorter measurement time thanks to the simultaneous measurement of up to 20 sample strips
  • Measurements over a broad range of temperatures thanks to a computer-controlled climatic chamber
  • Retrieval of stored information in tabular or graphical form
  • Meets ISO standard 6721-3:1994 but offers many improvements
