Paper Title:
Reliability-Based Optimization for Fatigue Maintenance Planning of Freight Car
  Abstract

The performance of bogie decreases according as traveling distance increases. Its causes were expected to be fatigue, wear, and deterioration. Especially, maintenance coat needs about triple than manufacture cost during required life in case of container and uncovered freight car. Freight car doesn’t adapt corrective maintenance which repairs a poor part after a trouble but use preventive maintenance which fixes a bad part before a trouble. There were a few researches on preventive maintenance such as inspect affairs and facilities management. They couldn’t estimate the operation reliability on railroad vehicle. Therefore, this study proposes the preventive maintenance procedure that predict repair period of end beam for uncovered freight car using reliability function and instantaneous failure rate on the basis of fatigue test and load history data.
