摘要:: 接触网系统是牵引供电系统中的重要组成部分，由于接触网系统的无备用特型，因此接触网系统必须安全可靠、性能良好。而接触网定位器作为接触网系统的重要组成部分，定位器的与受电弓匹配的合理性是高速电力机车安全取流的重要保证。目前，我国牵引供电系统高速铁路接触网装置融合了德系、日系、法系三种模式，而定位器主要有直型定位器和弧形定位器，主要材质均为铝合金。文章对三种铝合金定位器的材质、机械性能和受力性能进行了分析，同时分别对直型定位器、弧形定位器和受电弓的匹配性进行了研究。最后，根据研究结果分析得出三种铝合金定位器的优化建议，并且给出了我国后期高速铁路建设项目接触网定位器的采用建议。

Abstract:: Overhead contact system is an important part of traction power supply system. Because overhead contact system has no backup, it must be reliable and have good performance. As an important part of overhead contact system, the rationality of steady arm is the important guarantee of current collection with high speed electric locomotive. At present, overhead contact device in traction power supply system compromises three modes from Germany, Japan and France in our country. Curved steady arm and straight steady arm are common in high speed railway in China, and the main material of steady arm is aluminum alloy. In this paper, the materials, mechanical properties and stress performance of three kinds of aluminum-alloy steady arms are analyzed, at the same time, the matching between straight steady arm, curved steady arm and pantograph is studied. Finally, the optimization suggestions on the three kinds of steady arms are given, and also the suggestions on the adoption of steady arms in the following construction projects in high-speed railway are given.
