以常规自谱为特征建立了一套微型机故障诊断系统,并用该系统完成了对精密车床主轴轴承工作间隙的监测和识别;引进差谱概念,使识别精度大大提高;系统通过数据库对基准样本进行管理,使状态的扩展和信息的存贮及传递更加方便。附图7幅,表3个,参考文献6篇。 A set of microcomputer fault diagnosis system was established based on the characteristic of conventional self-spectrum. The system was used to monitor and identify the working clearance of the precision lathe spindle bearing. The concept of differential spectrum was introduced to greatly improve the recognition accuracy. The system, through the database, Management, so that the status of the expansion and storage and transmission of information more convenient. Figure 7, Table 3, 6 references.
