MULTIVARIATE ANALYSIS AND ASSESSMENT OF RELIABILITY OF POWER EQUIPMENT OF SELF-PROPELLED ROLLING STOCK OF THE RAILWAYS

Abstract

Static analysis and evaluation based on findings from long-term observations on operating equipment, forecasting and rationing of optimal reliability as well as the rational choice of technical solutions during their development and operation represent a practical challenge related to reliability of SSPS, as in any complex technical objects. The article presents the analysis and evaluation of calculation of reliability and the choice of technical solutions ensuring it during operations of electrical installations of self-propelled rolling stock of the railway. It also describes an example of solving a practical problem using standard and special methods of reliability theory and optimal solutions. A mathematical model of dependence has been determined, which allows predicting reliability of a synchronous generator of the automatic transmission when the initial resource is triggered for any real operating conditions and assigning optimal frequency of maintenance.
