摘　　要：目前,动力刀架振动测试方法的缺失及不完善严重制约了数控车床及车铣复合加工中心行业的发展。鉴于此,开发了基于虚拟仪器平台LabVIEW的三向振动检测系统。系统以三轴加速度传感器为传感器件检测刀架振动信息,采集到的信号经信号调理仪放大和调整,提高系统抗干扰性;通过对采集的振动信号进行频谱变换和频率信息的分析,可探究刀架振动原因进而采取相应措施有效减小振动;最后采集到的数据利用报表生成功能进行存储。In view of the scarcity and imperfection of power tool rest vibration test method so far,which has seriously limited the development of the industry of CNC lathe,lathe and milling composite machining center.A three-direction vibration test system based on LabVIEW is developed.The developed system adopts a three-axis acceleration sensor as vibration test component to test the vibration information of the power tool rest.To enhance the anti-interference ability of this system,the sampled signals are amplified and adjusted by the signal disposal instrument.Through the spectrum transformation and spectrum analyses of the sampled vibration signals,the vibration causes of the power tool rest can be inquired and the concern measurements can be taken to reduce the vibration effectively.Finally,the sampled data is stored by the report generation function.
