Aspekty ovlivňující přesnost lokalizace zdrojů akustické emise

Abstract

The topic of the submitted bachelor thesis is the analysis of factors that can significantly affect the accuracy of acoustic emission source localization. The introductory part of the thesis is devoted to the problem of acoustic emission in relation to source localization using iterative and non-iterative methods, including the necessary mathematical concepts. The following section deals with the design of an experiment that clarifies how the defined factors affect the localization accuracy. The penultimate section is devoted to a study that aims to assess the effect of the number of sensors entering the localization algorithm against a fixed and floating threshold for hit detection respectively. The paper concludes with an evaluation of the results obtained based on the experiment and the subsequent study.
