摘要

某机车现场运行时机械间变压器电磁噪声突显，产生刺耳的啸叫声，严重影响听觉。针对这一现象，开展了变压器现场和车间电磁噪声声学测试，了解其声学特性，在此基础上结合变压器实际安装情况及声传播特性，提出了声学包装优化方案，并对优化方案进行了声学仿真计算和试验验证。结果表明，优化方案能明显改善现场变压器电磁噪声水平，提高值乘舒适性，且成本较低。

Abstract

It was found that the electromagnetic noise of a certain transformer of a locomotive on site was prominent, resulting in harsh screech, which seriously affects hearing. In view of this phenomenon, the acoustic tests of electromagnetic noise of transformer were carried out in the field and workshop to study the acoustic characteristics, based on which the optimization scheme of acoustic packaging was put forward according to the actual installation condition and sound propagation characteristics of the transformer, and the acoustic simulation calculation and experimental verification of the optimization scheme were carried out. The results showed that the optimized scheme could significantly improve the electromagnetic noise performance of the transformer and the riding comfort with low cost.
