摘要
根据突尼斯内燃动车组项目技术规范中关于车内外噪声要求和评定标准,介绍了动车组噪声源、不同区域断面结构的声学优化设计、车内外噪声预测和采取的降噪措施,通过车内外噪声的测试,验证了预测的准确性,试验与噪声预测结果基本一致,噪声测量值达到了项目技术规范的要求。
According to the internal and external noise requirement and assessment standard of the technical specifications for Tunisia DUMs,this article introduces the noise source of DMUs,acoustics optimization design of different sections,noise forecast and reduction measures.The test result is consistent with the noise forecast,and the noise measurement value can meet the requirement of technical specifications for Tunisia DUMs.
