Rotational Analyses

Rotational Analyses

Rotational machinery can cause undesirable noises and vibrations. Examples of this not only include combustion engines and electric motors, but also turbines and other motor units such as turbochargers. The overall noise emitted by rotational machinery comprises the acoustic contributions from all the various individual components such as the drive shafts, gear units, bearings, belt drives and chain drives. The user can assign annoying noises and vibrations to the single components by means of the different rotation analyses in the PAK software.

The basic requirement for a meaningful analysis of rotational systems is an exact recording of the rotational speed, using high-resolution tacho inputs.
