Abstract: This paper investigates the design of a self-oscillation loop for the gyroscope system. The dynamic equations describing this system are analyzed using the method of averaging, and a criterion ...

Abstract: The effects of typical machining errors on the dynamic features of rod-fastened rotor bearing system (RBS) are studied in this paper. Three micron-sized machining errors are considered in a three-dimensional (3D) rod-fastened ...

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 ...

Abstract: Chloride-induced reinforcement corrosion is one of the major causes of durability failure of concrete structures in a salty environment. Because concrete is a kind of heterogeneous material, the effect of coarse aggregate ...

Abstract: Wear changes the contact state and contact stiffness of the interface between the ball and the outer raceway under the operation of a deep groove ball bearing, resulting in the change of reflection coefficient of the ...

Abstract: Different from the crack on the rotating shaft, the crack on the bolt, which is a connecting part of the bolt-disk combined rotor, is a kind of local defect. The local crack on the bolt under high pretension is always in ...
