Dynamic test rigs are used to determine the dynamic and static properties and the behavior of plastic and rubber parts. In contrast to steel, plastics and elastomers have strong dynamic characteristics and are effected by frequency, load and temperature. The determination of these properties requires special test rigs with special dynamic characteristics.

Each machine and each part that moves or is moved, such as bearings, motors, gearboxes cause dynamic effects, vibrations which radiate over surfaces airborne noise. Error in these parts change the dynamic forces, the part sounds different and feels different. These subjective differences can be measured but this is not always easy. Often the amplitude of the vibrations changes only insignificantly. The tactile or audible difference is often justified only by changes in a narrow frequency band. In the dynamic quality inspection only characteristic frequency bands are analyzed. Also sensor data are combined to view only certain directions. This result  is a reliable end-of-line testing.
