【摘要】 针对滚珠轴承故障诊断的应用实际,该文建立了基于相似性度量的故障诊断模型。该模型首先通过数据采集模块采集振动信号,再经降噪滤波模块对初始信号进行降噪、滤波处理,随后通过特征提取模块提取出降噪信号中的特征信号,将这些特征信息作为查询条件,通过数据传输模块发送给远程的数据库服务器,服务器接收到查询条件之后,将特征信息与数据库的故障信息进行相关性分析,最后得出诊断结果。更多还原

【Abstract】 Practical application of fault diagnosis for ball bearings, for this reason, an intelligent fault diagnostic model based on similarity measure is presented in this paper. This model is to firstly collect vibration signal via data acquisition, to de-noise and filter initial signal, and then take character signal extracted from de-noising signal as query parameters. Lastly, the data are sent to remote database server. After receiving query parameters, the final diagnosis can be got by analyzing the special signal and fault information after clustering.更多还原
