接触网铝合金铸件标准探讨

摘要

Based on a description of the application of aluminum alloy castings for OCS in domestic HSR(High Speed Railway),by comparing the similarities and differences in chemical composition,mechanical property,quality requirement,dimensional tolerance and so forth of aluminum alloy castings that are stated in the EN standards, the ISO standards,the ANSI stands as well as the national standards and the railroad industry standards in China.%在叙述接触网铝合金铸件在我国高速铁路应用情况的基础上,对比分析欧洲标准、国际标准化组织标准、美国标准、我国国家标准和铁道行业标准等在铝合金铸件的化学成分、力学性能、质量要求、尺寸公差等方面的异同点,提出我国国家标准和铁道行业标准修订建议.
