Abstract

The present invention describes an order tracking system (200) and method (100) for tracking at least one order from mechanical and / or acoustic vibrations generated by a periodic excitation process of a physical system. The order tracking system (200) comprises a means for obtaining (212) a mechanical and / or acoustic vibration data of a physical system and a means for obtaining (214) system reference data. It further comprises a means for combining (224) the mechanical and / or acoustic vibration data with the system reference data and a means for applying (226) a digital FIR filter to at least the mechanical and / or acoustic vibration data for deriving based thereon at least one order.

Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to methods and systems for studying vibrational and / or acoustic phenomena. More particularly, the present invention relates to methods and systems for tracking orders in the study or analysis of mechanical vibrations and / or noise of physical systems as well as to the application thereof.BACKGROUND OF THE INVENTION

[0002] Sound and vibration phenomena often are analysed in order to optimise them, e.g. to reduce the amount of disturbance that is generated for a user or the environment, to make a product compliant with specifications or with regulations set or to identify sources of disturbance, to control a system, etc. A known way for sound and vibration analysis is making use of order tracking. Order tracking typically is applied to variable-speed systems generating sound or another mechanical vibration.

[0003] Order tracking concerns the extraction of the complex envelope of order components from measured mechanical an...
