Training in vibration analysis

RISE offers a new training in vibration analysis, with a thorough review of the theory about signal processing, structural dynamics and vibration fatigue during three full days.

The training has three parts in a logical order. It is strongly recommended to participate in part 1 and 2 before taking on part 3. Part 1 and 2 are more generally applicable, while the final part is dedicated to the vibration integrity and fatigue impact. Hence, one could profit from part 1 and 2 only, for participants not interested in vibration fatigue. All parts are as useful for analysis of experimantal data as for post-processing of simulation results.

  1. Signals. Fundamentals and strategies for signal processing in vibration analysis, for the purpose of data explanation and data reduction. Signal classification, random vibration theory, Fourier transform, frequency and order spectra are covered, together with practical considerations on processing parameters.
  2. Structures. Explanation of how structures react to vibration and the resonance phenomenon and how linear vibration response can be simplified by superposition of independent eigenmodes. How we can identify structural properties from experiments using Experimental Modal Analysis, with or without measured forces, or Operational Deflection Shape analysis. Treatment of some non-linearities are covered briefly.
  3. Vibration fatigue. Learn about vibration test tailoring using Fatigue Damage Spectrum, for comparison of damaging potential between different vibration inputs, i.e. how to describe a measured vibration environment for a component and how to specify a damage equivalent vibration test. Also virtual vibration testing is covered, with frequency domain FEA, using random vibration base excitation, and fatigue post-processing. 

Objective

Participants will get good overview and structure of the rather wide subject scope, detailed knowledge of fundamental parts of vibration analysis and reference material to return to when needed. The training contains detailed review of theory and mathematics. Exercises are left for the students to perform after the training as the compressed schedule only allows for demonstration exercises by the teachers.

Target group

The training is suitable for test and calculation engineers with a university degree, both young and experienced. Also managers to specialists have good use of the overview and subject structure.

Teachers

Martin Olofsson is a researcher at RISE department Chemistry and Applied Mechanics, with extensive experience from vibration analys in product development work.

Kjell Ahlin is an internationally renowned expert in both digital signal processing and structural dynamics and appreciated lecturer. Former professor at Blekinge Technical University.
