Statistical Analysis Method for Fault Rate of EMU
摘要
Abstract
Based on the characteristics of EMU faults and the requirements for the operation and management in China,the accidents and faults of EMU are classified according to the severity of faults,and the reliability indices are formulated for Class A,B,C and D faults of EMU.According to the theory of reliability engineering,the definition and the formula of the fault rate index for every million km of EMU are given.The statistical analysis method for the fault rate of EMU is proposed.The change rule of the fault rate for one type of EMU in its life cycle,the effect of advanced repair and the periodic fault rule of certain components are analyzed.Results show that after the early inertia faults of EMU are effectively regulated,the fault rate has been significantly reduced and continued to be stable.The fault rate of the advanced repair is increasing gradually.After the advanced repair,there is a weak early fault period and then there is a dramatic decline.The trend analysis for the seasonal fault rate of the air-conditioning system shows that there is a significant peak of fault rate from June to August every summer and the maintenance measures should be strengthened.Example analyses show that the proposed method can be used to verify and analyze the fault rule of EMU based on the big data of operation and maintenance.关键词
