Rolling element bearings are one of the most precarious components and play an important
role in the effective operation of rotating machinery. Bearings are one of the foremost …

This work proposes a comprehensive numerical dynamic model of a flexible-rotor bearing
system based on the Hertzian and cubic polynomial nonlinear contact force methods. The …

Angular contact ball bearings (ACBBs) are key basic components of mechanical
transmission systems. Vibration characteristics of ACBBs have significant effect on the …

In this study, a multi-degree-of-freedom model is developed to investigate the vibration
characteristics of a feed system with nonlinear kinematic joints. Linear guide, ball screw, and …

Defects in rolling element bearings are foremost cause of failure in rotating machines. The
accurate and fast diagnosis of bearing defects like spall, dents, pits, cracks etc. on the …

In this paper, the stability analysis of a ball bearing system experiencing varying stiffness
coefficients is taken into account. The presence of variable stiffness may cause the system to …

The dynamic characteristics of system, namely the dam** ratio, natural frequency, and
mode shape are extracted from the frequency response function (FRF). Obtaining dynamic …

This paper deals with scale-fullscale models of rotor-bearing systems on rotating condition.
The investigation is focused on the gyroscopic effect, which causes forward and backward …

In this study, a new improved theoretical model of rotor-bearing system has been presented
to analyse the behaviour of the system due to the transverse crack on the rotor. Firstly, a …

The whirlwind milling (WM) technology is a competitive machining method, especially for
large screws. A rotating large screw subjected to a rotating and moving WM cutting force has …
