Probabilistic and Statistical Characteristics of Signals in Mirror through Transmission Technique on Multiple Reflections for Rod Cross Section Ellipticity Testing

Muravieva, O.V., Petrov, K.V., Gabbasova, M.A.

Abstract. This article suggests an approach to validation of new informative parameters in mirror through transmission electromagnetic-acoustic technique on multiple reflections for cylindrical object ellipticity testing, based on probabilistic and statistical analysis of multiple reflection series. The results of data array analysis obtained in the process of multiple reflection oscillogram modeling are presented. Behavior of probability density distribution, dispersion, root-mean-square deviation and asymmetry, depending on ellipticity value, is shown. Their applicability as informative parameters is introduced.

Keywords: ellipticity, rod, multiple mirror through transmission technique, probabilistic and statistical analysis
