Dynamic focusing of electroacoustic arrays in non‐desructive control composite materials

    Eugenijus Pileckas Affiliation

Abstract

Nowadays the application possibilities for composite materials for aviation are increasing, and monitoring their quality during production and exploitation is becoming more and more relevant. Acoustic non‐destructive control technologies provide promising possibilities for monitoring and analysing the characteristics and parameters of composites. This paper discusses an acceptable modelling method based on acoustic images of composite material analysis using a dynamic beam focusing method of an acoustic antenna array.


Santrauka


Vis plačiau naudojant kompozitines medžiagas aviacijoje aktualeja ir ju kokybes būsenos stebejimas konstrukciju gamybos ir eksploatacijos metu. Akustines neardomosios kontroles technologijos atveria, mūsu nuomone, perspektyvias kompozitiniu medžiagu charakteristiku bei ju parametru stebejimo ir tyrimo galimybes. Straipsnyje nagrinejamas priimtinas kompozitiniu medžiagu tyrimui akustiniu vaizdu formavimo būdas, panaudojant akustines antenu gardeles dinamini spindulio fokusavimo būda.
