Abstract
In order to simulate the reliability evolution process of Electric Multiple Unit (EMU) components under external shock and improve maintenance economy. The multi-level preventive maintenance method is established and the influence of maintenance period and allocation of multi-level imperfect maintenance on the maintenance economy are discussed respectively. Numerical experiments show that the multi-phase preventive maintenance model can reduce the maintenance cost rate. The analysis of bi-level imperfect maintenance capacity indicates that two-level preventive maintenance can extend the mileage of four-level preventive maintenance and three-level preventive maintenance can reduce the maintenance cost rate. Finally, some recommendations for the allocation of maintenance efforts are provided according to the different railway route features.
