Title:
BOLT FAULT DIAGNOSIS METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/273378
Kind Code:
A1
Abstract:
Disclosed in the present invention are a bolt fault diagnosis method and apparatus. The method comprises the following steps: S1, performing a bolt fault simulation test, and recording monitoring data of a bolt fault monitoring point; S2, simulating a bolt fault by means of a finite element method, and establishing a virtual fault case library; and S3, extracting a fault feature from the virtual fault case library, and performing artificial intelligence modeling on a real machine bolt fault. By means of the present invention, the problem in the prior art of it being impossible to perform effective diagnosis on all bolts by means of a limited number of test points is solved, thereby solving the problem of performing monitoring and fault diagnosis of a bolt group of existing devices.
