Abstract EN
Most existing techniques for machinery health monitoring that utilize measured vibration signals usually require measurement points to be as close as possible to the expected fault components of interest.
This is particularly important for implementing condition-based maintenance since the incipient fault signal power may be too small to be detected if a sensor is located further away from the fault source.
However, a measurement sensor is often not attached to the ideal point due to geometric or environmental restrictions.
In such a case, many of the conventional diagnostic techniques may not be successfully applicable.
In this paper, a two-channel analysis method is proposed to overcome such difficulty.
It uses two vibration signals simultaneously measured at arbitrary points in a machine.
The proposed method is described theoretically by introducing a fictitious system frequency response function.
It is then verified experimentally for bearing fault detection.
The results show that the suggested method may be a good alternative when ideal points for measurement sensors are not readily available.
