The nonlinear behavior of a rigid rotor supported by herringbone grooved journal gas
bearings (HGJBs) was investigated in this study. The two-dimensional narrow groove theory …

Due to their excellent stability and zero leakage capability, thrust bearings with herringbone
spiral grooves are frequently used in transmission mechanisms. However, the lubrication …

In order to improve the performance of the traditional constant-width herringbone grooved
journal bearing in a computed tomography tube under a high-temperature environment, the …

This paper presents the results of a theoretical and experimental investigation of the
potential of enhanced groove geometries to increase the bearing clearance of a …

The forced response of rigid rotors, supported by herringbone-grooved gas journal bearings
are investigated numerically and experimentally. The rotor configurations are varied by …

In this paper, a mathematical model is presented to identify the direct dynamic coefficients
(kxx, kzz, cxx, czz) of a pressurized bearing in a rotor-bearing system. The presented …

This paper presents an optimization-based methodology to predict the bearing coefficients
from the measured dynamic responses in a rotor supported on floating ring bearings. The …

To systematically investigate the behavior of fluid film bearing, the determination of optimal
parameters is of utmost importance. The core contributions of this article are as follows:(1) …

The design of an oil free turbocharger supported on herringbone grooved gas bearing was
formulated as a multi-objective problem, which was solved by coupling a reduced order …

This paper provides a comprehensive evaluation of crucial performances of hydrodynamic
journal bearings subject to inherent uncertainties from a nonprobabilistic perspective …
