Abstract: A method (200) for the characterization of vibrational and/or acoustic transfer path related data of a physical system (100) where vibration or acoustics may play a role. The method (200) has a step of receiving (210) input data for at least one input point of the physical system and/or response data for at least one response point of the physical system (100). The method (200) further has a step of receiving (220) at least one system response function between the at least one input point and the at least one response point indicative of the transfer of vibration and/or acoustic signals. The method (200) also has a step of applying (230) at least one parametric model characterising at least one load on the physical system as a function of the input data, where the parametric models are identified from the input data and/or response data and the physical system response functions.

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.
