| Abstract: | Based on the time-cumulated method,this paper expatiates the process of locomotive maintainability prediction and the calculation method of MTTR for systems and LRUs.And as an example of the air conditioning and ventilation system,it introduces the calculation of MTTR for locomotive systems and LRUs,and then obtains the MTTR for the locomotive.Finally,guidance to locomotive design from maintainability prediction and the limitations of the time-cumulated method are presented. |
