Dynamic Stress and Strain Measurements

L'étude et l'analyse des contraintes en phase de contrôle qualité détermine la fiabilité et la durabilité d'un composant. La simulation numérique basée sur les modèles par éléments finis (FEM) apporte une meilleure compréhension mais doit être validée par des données réelles. Le vibromètre laser 3-D à balayage de Polytec est la solution idéale puisque la caractérisation est précise et sans contact.

Polytec’s StrainProcessor
Strain Processor

Polytec’s StrainProcessor is a measurement extension developed for easy finite element model (FEM) updating and for comparisons to calculated stress and strain distributions. It comprises a set of hardware and software components enabling a PSV-400-3D Scanning Vibrometer – a well established tool for full field non-contact vibration mapping – to measure and analyze the dynamic strain and stress distribution on surfaces with high resolution and low noise.

The Scanning Vibrometer makes a series of non contact deflection measurements on a predefined grid using the laser probe to characterize strain at each point instead of attaching individual strain gauges. Thus, the test setup is fast and very repeatable with no mass loading from an attached transducer. Tests are fast and avoid the high cost of preparing and instrumenting the sample with strain gauges.
