Název v původním jazyce

Optimal sensor distribution for impact loading identification

Popis výsledku v původním jazyce

Problem of optimal sensor distribution for impact loading identification was studied on the composite airfoil segment. The segment is made of glass-epoxy composite with piezoelectric transducers glued on its surface. Numerical model of segment was assembled in finite element software Abaqus. The experimental modal analysis was performed and its results were compared to the results obtained from numerical model. Material parameters were adjusted using optimization where the difference between numerical and experimental results mentioned above was minimized. Furthermore, the segment was loaded by impactor and response was measured by piezoelectric transducer in selected location. The response was compared to one obtained numerically. Adjusted model was used for determination of optimal sensor distribution.
