摘要
介绍了动车组受电弓气动噪声的产生机理,在此基础上阐述了日本新干线动车组受电弓为降低其气动噪声而采用的措施,和德国ICE动车组的受电弓设计依据和试验结果的对比,根据国外动车组受电弓情况总结了减少动车组受电弓气动噪声所采取的措施,简单介绍了最近几年有关降低动车组受电弓气动噪声的相关研究成果,主要是进一步改进受电弓的弓角和弓头。
The mechanism of aerodynamic noise generated from high - speed pantograph is described. Based on it, the paper elaborated the measures how to decrease the aerodynamic noise generated by the pantograph of the Shinkansen series EMUs in Janpan, and the design criterion of ICE series in Germany and the contrast of test results. On the base of foreign EMUs pantograph it summarized the measures bow to reduce aerodynamic noise generated by EMUs pantograph. In addition, it introduced the achievement of diminishing aerodynamic noise from the high - speed pantograph in recent years, mostly further improvement focused on pantograph horn and panhead.
