Statistická analýzy zkoušky drátu krutem a střídavým ohybem

Abstract

The purpose of this study is examining the results of statistical tests of wire alternating bending and torsion. All tests as torsion and alternating bending test were performed on machines VSB - TUO. The torsion test was performed by using device named ZKZE 02/5, the alternating bending test was performed by using bending machine ZOZP 02/5.All data were statistically processed. During the test was used seven different diameters. Four diameters (3, 4, 1.6 and 0.6 mm) were tested in an alternating bending and three diameters (0.9, 1.8, 3.15 mm) were tested in torsion. All data were statistically analyzed using appropriate statistical methods. The best method for describing the measured data was the median and interquartile range.
