摘要
对高速动车组车下转向架区域噪声进行了分析研究,提出了一种多接口隔声降噪次地板结构,并通过试验验证了此种结构的可行性。
The noise in the bogie region under high speed multiple units is analyzed and researched.A subfloor structure with multi-interface for sound insulation and noise reduction is put forward,and the feasibility of the structure is verified through testing.
