摘　　要：机床声音信号包含着丰富的机床运行状态信息,可作为机床运行状态的判断依据。传统的机床声音信号采集设备成本高,功能单一。为提高机床声音信号采集系统的通用性、丰富声音信号采集系统的功能,并降低设备的成本,以机床、传声器、计算机等为硬件平台,基于Lab VIEW2012软件开发了机床声音信号采集与处理系统。通过实验证明该系统可以对机床的声音信号进行采集,并可进行初步的数据处理,证明了系统的可靠性,为机床设备故障诊断及预测系统的研究打下了坚实的基础。Machine tool sound signal contains abundant machine running status information,which can be used as a judgment of the running state of the machine tool. Traditional machine tool sound signal acquisition device is very expensive and has not much function. In order to improve the versatility and functions,and reduce the cost of equipment, the machine,microphone and computer are taken as hardware platform to develop the machine tool sound signal acquisition and analysis system based on LabVIEW2012. Experiments prove that the system not only ean acquire the sound signal of the machine tool,but also can process the data preliminarily. The system is proved to be reliable tor further studying fauh diagnosis and prediction system of machine tool equipment.
