Embodiment 1

[0047] see figure 1 , a kind of aerospace transmission mechanism analysis method based on fault data, described method comprises the following steps:

[0048] S1: Collect data, collect the speed of the inner and outer rotors of the aero-engine, and generate two key-phase signals to trigger the sampling of the corresponding vibration points;

[0049] S2: Data storage. During online monitoring, the set database is divided into configuration database and unit database. Each transmission mechanism corresponds to a unit database, and the configuration database stores relevant configuration information;

[0050] S3: Monitoring and analysis, comprehensive monitoring and analysis of the vibration signal of the transmission mechanism, divided into two modes: real-time monitoring and historical query, and the analysis results can be displayed on the monitoring host screen;

[0051] S4: Fault diagnosis, including a, detection and analysis data feature extraction; b, establishment of dat...

Embodiment 2

[0059] see Figure 2-3 A fault data analysis system adopted by an aerospace transmission mechanism analysis method based on fault data, comprising a data acquisition module and a detection host; the data acquisition module includes a sensor and a data collector; the monitoring host is provided with a management system module, a communication modules, data processing modules, data storage modules, monitoring and analysis modules, fault diagnosis modules, and alarm indication modules; the sensors are eddy current sensors and piezoelectric acceleration sensors; the eddy current sensors are arranged on the rotor rolling bearings of the transmission system, The vibration of the rolling bearing is measured, and the piezoelectric acceleration sensor is arranged on the inner wall of the transmission casing to measure the vibration of the casing; the data collector collects the speed and vibration signals of the aviation transmission system.

[0060] The management system module includ...

Embodiment 3

[0072] The difference from Embodiments 1 and 2 is that the data storage module is a database, and the SQLServer database is used to manage data and data backup. The database is responsible for receiving the data sent by the acquisition module, and corresponding to the query and update data requests of the data processing module.

[0073] The model of the eddy current sensor is 3300XL-11mm eddy current sensor; the piezoelectric acceleration sensor is Kistler9640A50 sensor.

[0074] This system is actually developed in C# language on the Visual Studio 2015 platform, uses ADO.NET technology to access the database, and cooperates with the SQLServer database to achieve efficient development of the system.

[0075] In addition, the fault diagnosis method is as follows: a. Detection and analysis data feature extraction, first perform data segmentation during original data processing, and then perform feature extraction for each segment of data, select time domain, frequency domain and...

Abstract

The invention discloses a method for analyzing an aerospace transmission mechanism based on fault data. The method includes the following steps: S1: collecting data, collecting the rotational speed of the inner and outer rotors of the aeroengine, and generating two key phase signals to respectively trigger the sampling of corresponding vibration point measurement points ;S2: Data storage. During online monitoring, the set database is divided into configuration database and unit database. Each transmission mechanism corresponds to a unit database, and the configuration database stores relevant configuration information; Monitoring and analysis, divided into two modes: real-time monitoring and historical query; S4: Fault diagnosis, including a, feature extraction of detection and analysis data; b, establishment of database; c, layering new data sets; d, obtaining new data faults Diagnosis results; S5: Fault management. After the diagnosis results are obtained, the cause and solution of each fault are given, and corresponding maintenance suggestions are given according to the fault type; the system method is reasonable and reliable.

Description

technical field [0001] The invention belongs to the field of aviation transmission fault equipment, and in particular relates to an analysis method of an aerospace transmission mechanism based on fault data. Background technique [0002] The supporting transmission system of the aero-engine is an important part of the aero-engine and the heart of the aircraft. Once a failure occurs, it often leads to serious flight accidents; the core components of the supporting transmission system are rolling bearings and drive shafts. The existing fault diagnosis methods mostly use The types of bearing faults are analyzed simultaneously without dismantling, and the vibration signal is proposed for aero-engine bearings and drive shafts. [0003] At present, my country is vigorously developing the aviation industry and has achieved certain excellent results. However, my country currently does not have an advanced and mature aviation transmission system fault detection and diagnosis system t...
