论述了适应新疆强风区电气化铁路接触网上部腕臂支持结构方案的比选过程。近年来国家对新疆地区铁路加大建设力度,既有及新建铁路均按电力牵引设计,其沿线多处为百里及三十里强风区,而风区内尚无成功运营的电气化铁路,接触网的受流质量直接影响机车的运营状态。在电气化铁路接触网设计中,腕臂支持结构作为接触网最基本的悬挂单元至关重要。主要是从国内、外腕臂支持结构的结构组成、连接方式、刚度等方面进行抗风适应性分析,特别是对多灾区国家腕臂支持结构的成功运营经验模式进行分析、比较,最终提出适应于新疆强风区的腕臂结构形式。
The comparison and selection process of adapting to the support structure of upper wrist arm of the electrified railway contact line in Xinjiang strong wind area is discussed. In recent years, the state has stepped up its efforts in building railways in Xinjiang. Both existing and newly constructed railways are designed on the basis of electric traction. There are a number of high-speed areas along the route, including Barry and Sanshili, and electrified railways with no successful operation in the area. The quality of the network directly affects the operating status of the locomotive. In the design of an electrified railway catenary, the arm support structure is essential as the most basic suspension unit of the catenary. Mainly from the domestic and foreign arm support structure of the structure, connection, stiffness and other aspects of the wind resistance adaptability analysis, especially for the multi-disaster support structure of the national arm supporting the successful operation experience mode analysis and comparison, and ultimately put forward to adapt Wrist arm structure in Xinjiang strong wind area.
