[ 1 ] - Preload Effect on Nonlinear Dynamic Behavior of Aerodynamic Two-Lobe Journal Bearings
This paper presents the effect of preload on nonlinear dynamic behavior of a rigid rotor supported by two-lobe aerodynamic noncircular journal bearing. A finite element method is employed to solve the Reynolds equation in static and dynamical states and the dynamical equations are solved using Runge-Kutta method. To analyze the behavior of the rotor center in the horizontal and vertical directi...

Introduction: Benzene, Toluene, Ethylbenzene and Xylenes (BTEX) are important parts of the volatile organic compounds (VOCs) family, which are widely used in many industries. These have been classified as carcinogenic compounds and the neurotoxic effects of BTEX have been reported; so, a screening evaluation of workplace air quality for determining BTEX may seem necessary. Methods: In order ...
