和谐1型系列交流传动重载高速电力机车轮对技术

Wheelset technique of series of type HX_D1 AC electric locomotive

和谐1型(含HXD1、HXD1B、HXD1C)系列交流传动重载高速电力机车是目前国内高速重载运输的主型机车,机车轮对重载技术的突破至关重要。文章主要介绍了和谐1型系列大功率交流传动重载货运机车轮对技术及相关标准规范的适用性,通过对车轮、车轴分析,材料研制及相关试验验证,表明机车轮对技术完全能够满足高速重载情况下的运用要求,并为今后机车向更高技术发展奠定了坚实的基础。

Series of type HXD1 AC electric locomotive is the main type of locomotive in domestic heavy loading and high speed transportation industry. As one of the core parts, the technology of wheelset is more important. This paper presents the applicability of correlative technology and standard of wheelset of series of type HX^I. By analyzing on wheel and axle, developing material and testing some examination, it finds out that wheelset can meet the requirement under the condition of high speed and heavy load, and make base for the technique development of wheelset in future.
