摘要
对动车组轴箱弹簧的结构与功能、现行检修规程、运用修与高级修发现的主要问题、检修周期延长可行性等方面进行了分析。通过实车跟踪试验,论证了动车组用轴箱弹簧高级修周期间隔由60万km延长至120万km的可行性。
Such aspects as the structure and functions of axle box springs on multiple units,the present inspection and repair code,main problems found in the operation repair and high grade repair,feasibility to prolong the inspection and repair cycle are analyzed.Through the actual car tracking test,the feasibility to prolong the high grade repair cycle of axle box springs on multiple units from 600 000 km to 1200 000 km is demonstrated.
