摘要
介绍声强法测定机车空调噪声的原理及其优点,并以某型机车空调机组为例,通过对该机车近场表面声功率及其频谱的分析,识别出该空调机组的主要噪声源和频率构成,结合国内外空调噪声防治的研究成果,提出机车空调噪声的综合控制措施。
The prdetermination ofinciple and advantages of the sound intensity method for noise locomotive air conditioner were introduced.Taking a type of locomotive air-conditioner as research object,the sound power and the spectrum on each segment of locomotive air conditioner were analyzed.Then the position of main noise source,main noise frequency and overall radiation intensity were identified.In addition,basing on the research achievements of air conditioner noise control,the comprehensive control measures were provided for the prevention of noise pollution of locomotive air conditioner.
