Abstract: This paper describes a measurement of lubricantfilm thickness in a roller bearing using a new ultrasonic pulserreceiver, which has a maximum pulse repetition rate (PRR) of 100 kHz. The experimental results show that a ...

Abstract: The stability and bifurcation of a flexible 3D rotor system are investigated in this paper. The rotor is discretized by 3D elements and reduced by using component mode synthesis. Periodic motions and stability margins are ...
