摘要:
利用现场测试的方法,采集客室与司机室关键位置的噪声数据,分别采用A计权声压级和线性声压级,分析了车速、轨道结构型式、钢轨几何线型等参数对地铁车辆车内噪声的影响。结果表明:车内噪声声压级与车速呈非线性关系;采用减振措施后隔振效率提高,但同时车内噪声也略微增加。
Abstracts:
Noise data of key positions in passenger compartment and driver′s cabin is collected from field testing. Influence of parameters such as train speed, track structure format and rail geometrical line shape on metro vehicle interior noise is analyzed respectively by adopting A\|weighted sound level and linear sound level. Results show that the vehicle interior noise sound pressure level and train speed has non\|linear relationship; the use of vibration reduction measures raises the vibration isolation efficiency, but the interior noise is also slightly increased.
