Embodiment Construction

[0053] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0054] Such as figure 1 As shown, the preferred embodiment of the present invention provides a method for identifying and locating the position of the abnormal sound of an aero-engine, which is used to accurately locate the position of the abnormal sound of the aero-engine, so that technicians can carry out timely maintenance on the position of the abnormal sound, and avoid unnecessary Necessary depot repair. The method for identifying and locating the position of the abnormal sound of the aero-engine comprises the following steps:

[0055] Step S1: testing the sensor;

[0056] Step S2: installing sensors at multiple positions of the aeroengine;

[0057] Step S3: collecting abnormal sound signals;

[0058] Step S4: Converting the format of the collected abnorm...

Abstract

The invention discloses a method for identifying and positioning an abnormal sound position of an aero-engine, which is used for accurately positioning the position where the aero-engine generates theabnormal sound. The method comprises the following steps: respectively mounting sensors at multiple positions of the aero-engine; acquiring an abnormal sound signal; performing format conversion on the acquired abnormal sound signal; and analyzing and processing the abnormal sound signal after conversion format so as to determine the accurate abnormal sound position. The method and a system for identifying and positioning the abnormal sound position of the aero-engine provided by the invention can avoid the situation that the aero-engine returns to the factory for repair due to wrong judgment, reduce unnecessary return loss, greatly reduce the maintenance cost of the aero-engine, and greatly improve the maintenance efficiency of the aero-engine.

Description

technical field [0001] The invention relates to the technical field of aero-engine detection, in particular, to a method and system for identifying and locating the position of abnormal noise of an aero-engine. Background technique [0002] Aeroengine is a kind of highly complex and precise thermodynamic machinery, which provides the power needed for flight for aircraft, and it directly affects the performance, reliability and economy of aircraft. Therefore, the detection of aero-engines is particularly important. [0003] At present, the detection method for the abnormal sound of the aero-engine is usually detected by artificial listening, but during the rotation of the aero-engine, due to the normal friction between the internal rotating parts, some noises will also be produced, which will cause interference to the artificial audible detection , affecting the judgment of technicians. Moreover, artificial listening detection has a great relationship with the work experien...
