摘要/Abstract

摘要： 受电弓精细动力学建模及固有振动特性分析对于进行结构优化设计,提高装备性能具有重要意义。对于结构可靠和性能优良的高速受电弓,不仅取决于整体动力学特性,局部振动特性也成为其中的关键环节。本文对受电弓精细动力学建模方法进行了研究,讨论了不同影响因素对受电弓固有振动特性的影响。研究表明,受电弓主要部件适当的质量分布和连接设置特性是获得符合实际结构固有振动特性的重要保证。

Abstract: Fine dynamic modeling and vibration characteristics analysis of pantographs have great significance in structural optimization design and equipment performance improvement. For high speed pantograph with reliable structure and excellent performance, not only the overall dynamic characteristics, but also the local vibration characteristics become the key link. The fine dynamics modeling method of pantograph was studied and it was found that the proper mass distribution of the main components in pantograph and their connection setting characteristics are the important guarantee to obtain the natural vibration characteristics of the actual structure.

Key words: high-speed pantograph, dynamic modeling, vibration characteristic, mass compensation, pantograph head suspension
