摘要
针对该型机车噪声要求低的要求,首先通过统计能量分析软件VA-One对机车噪音源进行分析,然后提出降噪方案,再通过软件计算并验证降噪方案的有效性。最后,按标准进行机车实际噪声测量。试验结果表明,计算软件准确地分析了机车噪声源,且机车降噪设计合理有效。
According to the requirements of the low noise requirements,firstly the locomotive noise sources are analyzed through the statistical energy analysis software VA-One,then the noise reduction scheme is put forward and its effectiveness is calculated and verified through the software. Finally,the actual locomotive noise is measured according to the standard. The test results show that locomotive noise sources are analyzed accurately by the calculation software and the locomotive noise reduction design is reasonable and effective.
