A Case Study on Lifetime for Electric Multiple Units

Currently, the use of the subway system as a public transportation has been an increasing demand due to the complex transportation structure in Korea. The subway system provides on time arrival and departure, relatively comfortable riding, and convenient access in the metropolitan area. Among several areas of the operation of the subway system, the safety of subway vehicle itself is of important because the rolling stocks carry the passengers, and the safety and reliability of rolling stocks are directly affected for the safety of subway passengers. In this research, various advanced engineering analysis techniques for the precision diagnosis assessment of subway EMUs have been introduced and the diagnosis assessment results have been used to provide the critical information for the lifetime assessment of EMUs.
