摘要
通常情况下所有地铁列车都要经过一年的可靠性由低到高的增长期后才能进入可靠性的稳定期,此后的运营故障数据才能代表列车的真实可靠性水平。目前国内多个地铁项目要求将车队的可靠性增长期缩短到首列车投入运营后的6个月内,这样车队中可靠性增长期最长的列车只有6个月,部分列车甚至没有可靠性增长期,这对车辆制造商来说是一个较大的挑战。通过对上海轨道交通10号线地铁列车的运营故障数据进行统计分析,总结了车队的故障高发区间、可靠性增长区间,验证了满足这种要求的可行性。
In general, only the field failure data in the sta- ble interval can reflect the reliability of metro vehicles, and all of them will enter to reliability stable interval after one - year reliability growth period. Several metro projects re- quire a short reliability growth interval of six months after the first train operation, thus the longest reliability growth period of the fleet is only six months in maximum, some trains have even not experienced any reliability growth pe- riod. In this paper, the statistical failure data of Shanghai metro Line 10 are analyzed, the early failure interval and reliability growth interval are summed up to demonstrate the feasibility in meeting the requirements.
