Fault Detection and Diagnosis Method of Firearms
Based on Periodic Characteristics of Automata |
| |
Abstract: | Aiming at the dynamic characteristics of automatic weapons, a real-time monitoring method based on the
movement period characteristics of the automata is proposed. For the purpose of fault analysis based on movement patterns,
a test system is built to analyze the monitoring reliability of the system''s movement period, and the virtual prototype
simulation analysis of the tested automatic weapon under a variety of typical faults is carried out to obtain the dynamics
parameters and corresponding period characteristics of its automata in the fault state. The test and virtual prototype
simulation results show that the monitoring method can accurately and effectively diagnose the typical faults such as
automata stagnation, recoil spring failure, extraction fault, etc., and can be used to monitor whether the movement of the
firearm is normal or not. |
