1. Tsuha, Natália Akemi Hoshikawa, 1990-. Modelo de força de contato de linha sob lubrificação elastohidrodinâmica aplicada a mancais de rolamentos radiais de rolo: Line contact force model under elastohydrodynamic lubrication applied to radial roller bearings.

Degree: 2019, Universidade Estadual de Campinas

Abstract: This work aims to propose a new line contact force model under elastohydrodynamic (EHD) lubrication and its application to rolling bearings. The reduced model of EHD contact force in function of stiffness and damping parameters has the main advantage of inserting the effects of the oil film into systems in order to make the model more realistic. As far as bearing are concerned, the contact between the bearing elements significantly affects its force equilibrium and its dynamic behavior and, consequently, the response of the rotating system in which it is inserted. The system of EHD equations was numerically solved using multilevel methods for both infinite and finite line contact. The proposed model of contact force is based on the terms of restitutive force and dissipative force. The restitutive force of the EHD line contact is calculated by an explicit force-displacement relationship and two independent parameters (stiffness and a surface separation constant). The dissipative contact force term is based on a linear viscous damping, which is estimated using the principle of conservation of energy for the transient problem. From the parameters of the reduced model of the contact force, the forces of the rolling radial bearing are obtained. Two commercial bearing models were studied: needle rolling element bearing and cylindrical roller bearing. The validation of the model was evaluated in experimental test bench of rotor dynamics. A numerical and experimental study of the frequency domain using frequency response function (FRF) was evaluated. In the time domain, the orbits of the proximity sensors were monitored and the discrete Fourier transforms (DFTs) of the amplitudes of the theoretical and experimental displacements were compared Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Cavalca, Kátia Lucchesi, 1963- (advisor), Nonato, Fábio, 1985- (coadvisor), Universidade Estadual de Campinas.
