Non-linear dynamic response of a balanced rotor supported on rolling element bearings
TL;DR: In this paper, the response of a balanced rigid rotor supported by rolling element bearings is studied, where the contacts between the balls and races are considered as non-linear springs, whose stiffness is obtained by using Hertzian elastic contact deformation theory.
Journal ArticleDOI
Analysis of Nonlinear Phenomena in High Speed Ball Bearings due to Radial Clearance and Unbalanced Rotor Effects
TL;DR: In this paper, the dynamic behavior of a high speed unbalanced rotor supported on roller bearings with damping has been studied, focusing particular attention on its nonlinear aspects, mainly due to Hertzian contact and radial internal clearance, and results show the appearance of instability and chaos in the dynamic response as the speed of the rotor-bearing system is changed.
Journal ArticleDOI
Vibration based performance prediction of ball bearings caused by localized defects
TL;DR: In this paper, the authors focused on accurate performance prediction due to localized defects (like spalls) of microns level on the bearing components, which is essential to the design for high performance.
Journal ArticleDOI
Analysis of mechanical properties of carbon nanotube reinforced polymer composites using multi-scale finite element modeling approach
TL;DR: In this article, a multiscale finite element (FE) modeling approach is proposed for studying the pinhole defects in CNT reinforced polymer composites, where two configurations of CNT i.e. armchair (5, 5) and zigzag (9, 0) are selected for analyses wherein C-C bonds at atomic scale are modeled as Euler beam.
Journal ArticleDOI
Vibration characteristics of porous FGM plate with variable thickness resting on Pasternak's foundation
TL;DR: In this paper, free vibration analysis of a tapered FGM plate with porosity has been performed, and the displacement model of the kinematic equation for the plates in the present formulation is based on the First-order shear deformation theory (FSDT).
