The operating speed of the rotating machinery often exceeds the second order or even
higher order critical speeds to pursue higher efficiency. Thus, the second mode whirl/whip …

A detailed journal bearing analysis for accurate evaluation of film dynamic characteristics is
presented. The new formulation is based on a local perturbation of the oil film at each …

Influence of turbulence on the stability characteristics of a water lubricated journal bearing is
analyzed. Locus of the journal centre is plotted using the non–linear transient analysis …

ABSTRACT A set of simple expressions is deduced for static and dynamic parameters
associated to hydrodynamic journal bearings (JB). The behavior of this system is governed …

In this paper, the static and dynamic performance characteristics of journal bearing in terms
of load capacity, attitude angle, end leakage, frictional force, threshold speed and damped …

Abstract Effects of shape errors on the dynamic behavior of externally pressurized air journal
bearings are studied. A semi-implicit numerical scheme is used in order to reduce the …

A numerical THD model that takes into account mechanical and thermal deformations of a
compliant lining is used to investigate the influence of compliance on dynamic …

Aiming at the oil film instability of the sliding bearing at high speeds, a rotor test rig is built to
study the non-linear dynamic behaviours caused by the first-and second-mode instability. A …

Microrobots are promising tools for the treatment of biological cells because of their lack of
skill dependence, high throughput, and high repeatability. Integration of a microfluidic chip …

Most studies on dynamic coefficients of bearings are focused on evaluation using different
analytical methods. Minimal emphasis is given to the level of influence of each geometrical …
