Reliability means that a product maintains its initial quality and performance at certain period of time(time distance cycle etc) under given condition without failure. Given conditions include both environmental condition and operating condition. Environmental condition means common natural environment such as temperature humidity vibration and working condition means artificial environment such as voltage current load install place hours of use which occurs during using the product. In the field of railway vehicles although components of railway vehicles with reliability are the trend of mandatory as persisting period of railway vehicles is extended using components of railway vehicles is insufficient for the practical reliability assessment. but the meaning of the first railway operating agnecy to acquire the parts in the field the data suggest the reliability of products if you can and can show the reliability of modular units and modular units can provide the reliability of if you can present reliability of the entire system is thought to be here In this study lifespan of micro-switch for master controller is analyzed and prediction is performed based on its field data considering the special circumstances of railway vehicles operating agency such as a large number of trains operates on the same line.
