Research On The Maintenance Management Of Chengdu-chongqing Region CRH1 Series EMUs

Modern equipment has large, complex, mechanical and electrical integration, fault rule is no longer simply follow "wear and tear" theory, repair more frequently, scope of repair more, the introduction of early fault may be more. Thus, the creation of a "on the reliability center maintenance system, emphasizing a more scientifically determine the maintenance objects, select the maintenance, the maintenance time control. At present, with the modernization of the high-speed railway and heavy load transportation technology, some developed countries(Western Europe and the United States) to the railway technical equipment maintenance theory of ongoing extensive and in-depth research, in reliability engineering for the basic theory of rams(reliability, availability, maintenance repair and safety), the reliability centered maintenance(RCM:Reliability-Centered maintenance), and life cycle cost and the maintenance strategy(LCC:Life cycle cost) to obtain the many achievements.Due to the special geographical and climatic conditions of the Chengdu Chongqing area high temperature, heat, acid rain and mountain railway, the EMU Operation and maintenance is facing a severe test. From the present stage of Chengdu Railway Bureau of high speed EMU overhaul put forward the new demand of consulting in recent years at home and abroad of the inspection and repair of high speed trains new trends, and to maintenance of Chengdu Bureau at this stage as the foundation, using the reliability centered maintenance analysis method, of EMU the repair process of the applicability and effectiveness of analysis and evaluation, and initially put forward in reliability theory of management mechanism.
