Reliability Analysis of the Hydro-System of Excavator SchRs 800 Using Weibull Distribution

Abstract:

In this paper is given the use Weibull distribution (WD) as theoretical reliability model for analysis of the hydro-system of excavator SchRs 800, which is accepted on the basis of Pearson (χ²), Kolmogorov-Smirnov (KS) and Cramér-von Mises (CvM) goodness-of-fit tests. The time of work without failure of the hydro-system of excavator SchRs 800 for accepted Weibull model of reliability for probability of 50 % is T_50%=0.3417⋅10³ [h], for probability of 80 % is T_80%=0.1884⋅10³ [h] and for probability of 90% is T_90%=0.127⋅10³ [h].
