Reliability based calculation of repairing interval of locomotive wheel axles

The paper introduces the conclusions of lifetime research of the locomotives at Saigon Locomotive Enterprise (SGLE) in Vietnam. This research bases on reliability theory to define the gamma-percent lifetime of locomotive. The authors build the CT2010 spreadsheet for empirical statistical data process of the locomotives. CT2010 can rapidly calculate the gamma-percent lifetime and define the suitability of seven probability distributions including exponential, normal, gamma, lognormal, Weibull, Rayleigh, and Maxwell distribution.
