Numerical Model of Airfoil Segment for Impact Loading Identification

Popis výsledku v původním jazyce

Problem of impact loading identification and impact localization was studied on the composite airfoil segment made of glass-epoxy composite and on numerical model. The airfoil segment was loaded by impactor and response was measured by sensors. Two typesof sensors were used; piezoelectric transducers which were bonded to surface and non-contact laser displacement sensors. The sensor response to loading in individual impact point was characterized by transfer function which was determined from measurement. Transfer functions were used in inverse process to estimate impact force and impact location from sensor responses. Identification errors for different impact locations and sensor types was determined and discussed. Numerical model of the airfoil segment was created in finite element software and measured responses on impact loading were compared to results from numerical simulation. Numerical model was then utilized within the identification process and identification errors from nu
