FVA714 Metrological Determination of Torsional Vibration Parameters

 

Results

A procedure has been developed and documented to use measurements for the automated identification of parameters in a physical vibration model. Additionally, a software prototype has been implemented in Matlab to verify the method.

Motivation

Simulation of vibration behavior of drivetrains provides good insights about the dynamic properties of a system at the early stages of product development. Particularly, this includes the identification of critical operating points for resonances in the system as well as the creation of time-dependent load functions. Furthermore, the existing approaches in measurement and simulation domains suffer from several limitations.

Research objectives

The objective of this project is to develop a procedure to use measurements for automated identification of the parameters in a physical vibration model and its implementation in a software prototype. The following goals were pursued:

  • Facilitating the use of measurements to determine parameters for torsional vibration modeling
  • Defining a method that can be applied with only a limited experience in modeling and simulation
  • Creation of a software prototype to evaluate the method
  • Transferring the obtained results into industrial applications
