Wheel set condition monitoring is implemented by a vibration sensor mounted on the axlebox housing, or integrated into the axlebox bearing, to provide information that can be used to determine the condition of the wheel set, such as wheel flats and wheel shape. The real-time calculation also uses information about the shaft speed.
Typically, vibration sensors are installed at or near the bearings where sensor access to the rotor and survivability of sensors dictate. However, midspan locations between the bearings are where operators would most like to measure vibration levels but cannot because of inaccessibility and the hostile environment for vibration sensors.
