Vibration Measurement Pitfalls

| 2021:803 | Åsa Collet, Jessica Fromell, Krister Larson, Efterklang Part Of Afry
Vibration measurements is an important part of the nuclear power plant condition monitoring.

Knowing that the measured results are correct is vital. If you are an experienced user you are often aware of all the common pitfalls and know how to avoid them, but for an inexperienced user it is valuable to get information on how to avoid common pitfalls. In this project experienced vibration experts have been interviewed and common pitfalls are documented. It is important to share experience on pitfalls, it is often very difficult and time consuming to detect, investigate, analyze and to solve the mistakes in measurements.

    Cavitation induced vibrations in orifice plates and a partially closed valve

    This study aims to experimentally investigate flow-induced vibrations and cavitation in single-hole and multi-hole orifices and a partially closed Stafsjö valve. The goal is to provide experimental data for validating Computational Fluid Dynamics (CFD) models.
