system HUMS - Opis:
- In the kinematic system of airplanes and helicopters there are critical elements of structures on which accelerated symptoms of fatigue use are observed, e.g. in the form of: damage (peeling) of the raceway of the rolling bearing, fatigue undercuts of the gears. The article presents a method for diagnosing a kinematic system based on an on-board generator (state observer). At the beginning, some of the research problems occurring in helicopters, based on their own research data, were approximated. Particular attention was paid to the phenomenon of resonance of rolling bearings and resonance excitation of a pair of gear wheels under its influence. The effectiveness of detection of such resonance phenomena by means of the proposed diagnostic method was presented. The conclusion summarizes the conclusions that the method provides a reliable diagnosis and would be a valuable complement of previously used HUMS. The directions of further research on the development of the diagnostic method were also indicated.
