ANALYSIS OF VARIANCE IN THE STUDY OF PROBLEMS IN SMALL SCALE PRODUCTION OF TWO-STEP FLOATED GYROSCOPES

Annotation

Problems arising in the small-scale production of two-stage float gyroscopes, are considered. Results of a study of variances as applied to these problems are presented. The experience in the use of dispersion analysis in the study of gyromotor rotors quality using MS Excel program is discussed. The influence of the human factor on the FD-factor of the adjusted device was investigated by means of one-factor analysis of variance. As a result, the hypothesis H1 about the presence of such influence is accepted, and the null hypothesis about the absence of the human factor influence on the integral estimation of the accuracy of the azimuthal gyroscope is confirmed. Results of the single-factor analysis of variance confirming the alternative hypothesis H1 on the significant effect of melting on the magnetic energy of the rotor blanks, are presented. The absence of the influence of difference in melting on the run-out time of the gyromotor in three orientations and on the values of consumption currents in the steady state mode is established. Two-factor analysis of variance is used in the study of the final FD-factor of the device. Results related to the effect on two independent variables — the human factor and the type of stator compound — are presented.
