以３８６微机为主体建立了振动信号采集和分析系统。此系统在不需要人工过多干预的情况下，能实现对成品轴承振动质量的诊断且诊断准确可靠，在轴承振动超差的情况下，能自动判明原因。软件系统用ＴｕｒｂｏＰａｓｃａｌ语言编制，全部汉字显示菜单，应用方便。该系统还可以推广应用于其它机械振动信号的采集和分析 386 microcomputer as the main body to establish a vibration signal acquisition and analysis system. The system can realize the diagnosis of the vibration quality of the finished bearing and the diagnosis is accurate and reliable without the need of manual intervention. When the vibration of the bearing exceeds the tolerance, it can automatically identify the cause. Software system using TurboPascal language, all Chinese characters display menu, easy to use. The system can also be widely used in other mechanical vibration signal acquisition and analysis
