One important facet of CBM+ is to formulate the assessment of the system based upon objective evaluation of degraded performance or impending failure. Only when the objective evidence substantiates the need to perform a maintenance action would the system be pulled in for maintenance. Viability and acceptance of predictive measures and appropriate metrics to ensure success have crippled efforts to...
This paper presents a new bearing fault diagnosis based on detecting the impulses in the vibration signal caused by the damage. These impulses excite the natural frequencies of the system to resonate. The proposed algorithm uses wavelet packet decomposition (WPD) to localize the subband containing the frequencies of the system resonance. Decomposition of the vibration signal is performed only for...
A new method of early fault diagnosis for manufacturing system based on machine learning is presented. It is necessary for manufacturing enterprises to detect the states of production process in real time, in order to find the early faults in machines, so that the losses of production failure and investments of facility maintenance can be minimized. This paper proposes a new fault diagnosis model,...
