摘　　要：随着机床向高速、重载、高精度以及人机和谐方向发展,对噪声的控制技术也提出了更高的要求。现利用信号检测仪器检测某型立式铣床噪声、振动信号,通过数据处理后进行故障诊断,找出噪声与振动源,并进一步进行噪声质量分析,找出突出噪声产生的基本原因,提出降低噪声的几点措施,为以后类似的机床降噪研究提供借鉴。Along with the development of machine tool to high-speed, heavy -duty, high-precise and man-machine harmonious, higher requirements are put forward for noise control technology. Signal detection instrument was used to detect the noise and vibration signal of a vertical milling machine. Then data processing and fault diagnosis were made to identify the noise and vibration source. Further analysis was made for the noise quality of the vertical milling machine to find out the reasons of producing the prominent noise. Several measures were put forward to reduce the noise. It provides reference for the future noise-reduction work.
