Locomotive Reliability Assessment Method

Abstract. The authors describe the analysis of current state problem under consideration. A definition "averaged failure flow parameter" is given. periods traction rolling stock life cycle are considered. assumption event distribution laws exponentiality introduced, which makes it possible to obtain expressions main reliability indices in analytical form. work depot service locomotives ensure required and readiness during their normal operation has been assessed. introduction term "readiness" into modern practice estimation initial data for calculating indexes locomotive uptime presented. Calculated values no-failure electric obtained. calculated internal technical availability coefficients compared with similar indicators established by specifications. Control procedures were performed determine compliance each set (EP1, 2ES4K) requirements. As a result comparing factors (for EP1 2ES4K analogous specifications (EP1 was determined that surveyed comply control requirements, run question does not fully requirement. And meets but error value higher than 20%. To clarify both events, necessary increase mileage interval repeat procedure determining method assessing identify existing shortcomings form measures improve quality operation.
