成都地铁1号线列车原装为日本一系弹簧,运用半年后的蠕变量达到了10 mm,本文通过理论计算分析和实验,研究分析一系弹簧国产化的可行性。文中描述的新型国产一系弹簧在运营车辆上试装后得出的一系列经验数据,为地铁一系弹簧国产化提供借鉴。一系弹簧国产化不仅提高了一系弹簧使用寿命,而且降低了维护费用。

The train in Chengdu Metro Line 1 originally adopted Japan′s primary spring, the creeping reached 10mm after half year. In this paper, analyzes the feasibility of primary spring′s localization through theoretical calcu-lation analysis and experimental research. The empirical data are obtained after the test of the new type of primary spring which made in China. Localization of primary spring not only improves the service life of the primary spring, but also reduces the maintenance cost.
