摘要
从钢轨质量、承载能力、允许轨温差、钢轨硬度、轮轨匹配等方面对阿根廷地铁项目所采用54E1钢轨进行优化设计及分析探讨,并对基于轮轨硬度匹配下的轮对优化选型进行合理化设计。
From such aspects as rail quality,carrying capacity,permissible temperature difference of rail, rail hardness and wheel-rail matching,54 EI rail used in Argentina metro project is optimally designed and comprehensively discussed,and the optimal selection of wheelset is rationally designed based on wheel-rail hardness matching.
