Analysis of the ratio of shifts and extreme members of aggregates and samples by resource and strength
Incoming article date: 02.10.2018The simulation variances of the final volume considerably simplifies the solution of certain problems of reliability. The collection of information for aggregates of large volumes is impractical because of the duration and high cost. Therefore, the analysis and calculation are subjected to a representative sample. To move from sample data to finite volume population parameters, an analytical method for determining the Weibull parameters for the population was used. Analysis of the analytical method for determining the parameters of the three-parameter Weibull distribution for the aggregate confirmed the possibility of using the method of modeling statistical data of strength and life of parts and components of machines. The calculations proved that in practice it is possible to use both the value of the shift parameter and the value of the extreme terms of a number of the population.
