Embodiment Construction
[0042]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0043] Such as figure 1 and figure 2 As shown, the present invention provides a vibration fault detection system for aero-engines. Since different faults of aero-engines have different reflection degrees at different operating frequencies, this embodiment selects aero-engines in the order of operating frequencies from low to high. Work in sequence, and identify new vibration faults of aero-engines by analyzing the vibration amplitudes at different operating f...
