NUMERICAL MODEL OF COMPOSITE AIRFOIL SEGMENT WITH PIEZOELECTRIC SENSORS

Popis výsledku v původním jazyce

Numerical model of airfoil segment with piezoelectric sensors was created in commercial finite ele- ment software Abaqus and its response to impact loading was compared with experimental results. The wing segment is made of woven glass epoxy composite with varying number of plies and type of weave. The material properties were experimentally determined form tensile tests and used in finite element model of rectangle plate. Results from experimental modal analysis of composite rectangle plate made of thesame material as the segment were compared to results from numerical analysis and parameters of numerical model were adjusted. Finally numerical model of whole segment was cre- ated and validated on experimental results from experimental modal analysisof whole model. More- over piezoelectric sensors ware glued to the segment and their response to dynamic loading was com- pared to results from numerical simulation.
