本资料的功能为:运用数学统计方法和时间序列分析方法对原始振动信号进行分析,获取相应的时域,频域,频域及时间序列模型参数并以此作为特征参数,然后运用距离区分技术进行评估,选取敏感的特征参数作为ART-similarity分类器的输入并进行训练,最后便可识别出设备的性能状态。
基于YU范数对承不同预紧状态的分析,针对进给系统所采集的数据样本事先不知其对应的状态时,则可利用基于YU范数的ART-Similarity监督分类器对其进行诊断分析。针对基于Yu范数ART-Similarity的算法,我上传的文件即为该算法的MATLAB代码,在matlab中,把文件中的关于"ryu0jin32feat.txt" "ryu1jin32feat.txt" "ryu2jin32feat.txt" "ryu3jin32feat.txt" "ryu4jin32feat.txt" "ryu5jin32feat.txt"文件的路径修改正确,即可正常运行,这些文件的主函数为"jingeiART.m"(This information is the function as follows: the use of mathematical statistical methods and time series analysis of the original vibration signal analysis, to obtain the corresponding time-domain, frequency domain, frequency domain and time-series model parameters and as a characteristic parameter, and then distinguish between the use of distance technology assess, select the characteristics of sensitive parameters as the ART-similarity classifier input and for training, the final performance of the device can identify the state.
YU-based norm of the bearing preload status in different analysis systems for feeding the data collected samples know beforehand that the corresponding state, can make use of norm-based YU supervision of ART-Similarity Classifier diagnosis of them. Yu-based norm for the ART-Similarity of the algorithm, I uploaded the file shall be the algorithm MATLAB code, matlab, they have replaced the file on the "ryu0jin32feat.txt" "ryu1jin32feat.txt" "ryu2jin32feat.t)
