In this paper, the aero-engine test with inter-shaft bearing fault is carried out, and a dataset proposed for first time based on vibration signal of rotors casings. First, rig real established, driven by motors equipped lubricating system. Then, disassembled assembled following specification process, artificial replaced. Next, conducted at 28 groups high low pressure speeds. Six measuring points are arranged, including two displacement sensors to signals rotor four acceleration casing. The...
Current methods used for the measurement of stiffness and damping spindle motor bearings in hard disk drives use a vibration base driven by an external actuator. Acceleration sensors displacement installed onto are then to measure acceleration runout, respectively. Outputs from these analysed calculation damping. The method, direct monitoring total damping, proposed this article does not require any additional sensors, neither it Vibration is generated introducing known value imbalance...
