Expert-Breakfast in Zurich: How do you get to the root cause of noise and vibration issues?

Download agenda & speaker bio

By using transfer path analysis (TPA), manufacturers mathematically evaluate noise contributions from the source to the receiver. This methodical approach to vibro-acoustic design helps to identify which components and structures contribute to specific noise and vibration issues. The results are used to optimize the design by choosing the most optimal and efficient modification to resolve the problem. The TPA methodology gives complete insights into the noise and vibration behavior, leading to faster troubleshooting and better product refinement.

In this seminar, you will learn how to master this complexity, how to estimate the operating forces, and how to get to the root cause of noise and vibration issues. All methods will be explained and industrial examples will be discussed. Your specific questions are welcomed and will be addressed during the seminar. For further questions about this event, please don’t hesitate to contact:

You will learn:

  • The fundamental difference between classical TPA and operational TPA and what are the advantages/pitfalls for each of them.
  • How to get correct operational forces when they are physically close to each other (strain TPA).
  • How to get forces that are a function of a component and that can be used in simulation to be used in a different configuration (component TPA).

Fundamentals of TPA

How to speed up the TPA process by using operational TPA and what to pay attention to. The classical TPA process (Structure-borne loads estimation, airborne loads estimation, acoustic source quantification, gathering high-quality FRF data).


Strain TPA

Classical TPA is normally done in the frequency domain and the measurements are typically accelerations and pressure. However, there are situations where strain measurements instead of acceleration can provide better results.




Time TPA

For certain transient applications, a frequency domain TPA won’t provide a correct insight into the problem since the problem is rather time-related than frequency related. Doing a TPA analysis in the time domain resolves this issue.


Component-based TPA (blocked forces TPA)

The forces obtained with classical TPA are the correct connection forces for a particular configuration of the structure. However, these forces can’t be ported to a structure with a different configuration. Component TPA allows you to obtain forces that are the property of the component, and these component forces can be converted into reaction forces for a particular configuration.
