Problems solved by technology

[0003] The existing analysis system for bearing fault data is mainly used to record the information related to the installation position of the bearing and the basic information of the bearing fault. Carry out detailed analysis and records on the causes of bearing failures; there is no basis for rapid troubleshooting and bearing selection decisions in the later stage, and there is no approved standard for data collection and standardization, so it is impossible to screen the collected data

Embodiment 1

[0054] like figure 1 As shown, this embodiment provides a method for constructing a bearing fault dictionary, which specifically includes the following steps:

[0055] S1: With the bearing as the head node, construct a bearing configuration tree according to the subcomponents of the target bearing structure;

[0056] S2: Define the fault analysis field according to the bearing configuration tree;

[0057] S3: Fill the fault analysis field according to the obtained bearing sub-component fault data set, and construct a bearing fault dictionary.

[0058] In the step S1, currently in the existing MRO system, the bearing exists as the last node in the configuration; and in this embodiment, the bearing at the bottom position of the configuration in the existing MRO system is further refined , expand the configuration tree, create a complete bearing structure, and get the bearing configuration tree.

[0059] In this embodiment, in order not to affect the functions of the existing ...

Embodiment 2

[0104] This embodiment provides a bearing failure analysis method, including the following steps:

[0105] Generate a bearing fault ticket to be confirmed according to the identification result of the bearing fault;

[0106] The bearing fault dictionary construction method described in Embodiment 1 is used to obtain the bearing fault dictionary, and the bearing fault information is filled in the bearing fault ticket to be confirmed according to the fault analysis field of the bearing fault dictionary.

[0107] In this embodiment, the bearing fault ticket to be confirmed involves two types of bearing fault entry methods, including the out-of-factory fault ticket and the in-factory fault ticket, and different fault entry contents are set: the out-of-factory fault ticket includes the location of the bearing fault (referring to the bearing unit configuration of the MRO system), fault information, etc. (referring to the refined bearing fault dictionary of the MRO system), and suppo...

Embodiment 3

[0109] This embodiment provides a system for building a bearing fault dictionary, including:

[0110] The bearing configuration tree building module is configured to use the bearing as the head node to build a bearing configuration tree according to the subcomponents of the target bearing structure;

[0111] a field definition module configured to define failure analysis fields based on the bearing configuration tree;

[0112] The field filling module is configured to fill the failure analysis fields according to the obtained bearing sub-component failure data set, and construct a bearing failure dictionary.

Abstract

The invention provides a bearing fault dictionary construction method and method, and a bearing fault dictionary analysis method and system. The construction method comprises the following steps: with a bearing as a head node, constructing a bearing configuration tree according to the subparts of a target bearing structure; defining a fault analysis field according to the bearing configuration tree; and filling the fault analysis field according to the obtained bearing sub-component fault data set, and constructing a bearing fault dictionary. According to the bearing fault data analysis method based on motor train unit bearing localization, the problem of collecting bearing part fault data is solved, correlation data are analyzed, and the method can be used for guiding subsequent bearing design and manufacturing.

Description

technical field [0001] The disclosure belongs to the technical field of bearing fault analysis, and in particular relates to a method for constructing a bearing fault dictionary, an analysis method and a system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The existing analysis system for bearing fault data is mainly used to record the information related to the installation position of the bearing and the basic information of the bearing fault. Carry out detailed analysis and records on the causes of bearing failures; there is no basis for rapid troubleshooting and bearing selection decisions in the later stage, and there is no approved standard for data collection and standardization, so it is impossible to screen the collected data. [0004] In addition, different bearing structure types and different operating conditions have diff...
