Center Damping Test Rig

Alfa Acoustics center impedance damping loss factor measurement setup is designed to meet stringent test requirements of damping loss factor measurement. This method is also called as mechanical impedance method. When the impedance (F force/ V velocity) is measured in the central exciting method, the resonance frequency and anti-resonance frequency appear alternately.

At the resonance frequency, the excitation power is very small, and the specimen is vibrated greatly, while at the anti-resonance frequency, the excitation power is great, and the specimen is not vibrated much. This method is mainly applicable for materials used in ground vehicles, marine products, and aircrafts.
