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 generation mechanism of the aerodynamic noise of the pantograph of the EMU is introduced. Based on this, the measures taken by the pantograph of the Japanese Shinkansen EMU to reduce its aerodynamic noise and the design basis and test of the pantograph of the German EMU According to the situation of the pantograph of the EMU abroad, the measures taken to reduce the aerodynamic noise of the pantograph of the EMU are summarized, and the related research results on the aerodynamic noise reduction of the pantograph of the EMU are introduced briefly in the last few years, Improve pantograph bow angle and bow head.
