Abstract

The study presents a dynamic model for the resistance forces to the rotation of a journal in a lubricated sleeve bearing at low speed. The resistance forces include the sliding friction as well as the presliding Dahl effect, namely, elastic force due to the compliance in the system before the force reaches the break-away magnitude when sliding initiates. Both the stiffness of the surface asperities and the elastic support of the bearing are considered for the presliding rotation of the journal. The model is based on the physical principles of hydrodynamic lubrication as well as the dynamics of the system.

The model shows that the instantaneous friction is not only a function of the velocity at that instant, but also depends on the velocity history. The model predicts hysteresis-type friction curves for oscillating velocity, in agreement with previous experiments. The model may be useful to improve the precision of motion in feedback control systems with friction.

Systems with dry friction exhibit very complex behavior and, therefore, have to be analyzed accurately. At the same time, assumed friction model has to predict numerous known features and characteristics, resulting from friction action, such as presliding displacement [1–7], varying breakaway force [8,9], friction memory and hysteresis [10,11], Stribeck effect [12], stick-slip motion [13–18], etc. However, it is difficult to implement a model which would include all of the mentioned phenomena simultaneously.
The phenomenon of frictional slipping and sticking is one of crucial problems in mechanical engineering. This paper is focused on the numerical analysis of vibrations induced by friction in oscillator model which assumes an influence of the normal degree of freedom on the friction force. Analysis of Poincare maps, time courses and corresponding spectrum of Lyapunov exponents of the proposed three degrees of freedom dynamical system is demonstrated. It is revealed that the friction force, acting on the main slider, reflects dynamic behavior of the system response, i.e., some synchronous correlation between them is observed, even in the range of hyperchaotic behavior of the system, characterized by two positive Lyapunov exponents. On the other hand, an interesting effect of the coexistence of irregular friction force at the contact point of the frictional brush and ground surface with the regular response of the system in the quasi-periodic regime is reported.
Balancing energy to estimate damping parameters in forced oscillators
2006, Journal of Sound and Vibration
This study makes use of an energy balance to identify damping parameters in mechanical vibration systems. By balancing the energy input as registered in the force–displacement relationship of the real system against the energy lost theoretically in a damping model with unknown parameters, the identification algorithms are developed. We apply the estimation equations to both numerical and experimental systems, modeled with Coulomb plus viscous damping, at resonance to show the effectiveness and reliability of the new identification method. The equivalent viscous and dry-friction damping estimates obtained from the experimental system are compared to those obtained from the forced-resonance method to show their consistencies.
Identifying Coulomb and viscous damping from free-vibration acceleration decrements
2005, Journal of Sound and Vibration
A new damping-identification method for the simultaneous identification of Coulomb and viscous damping effects from free-vibration acceleration decrements in a damped linear single degree-of-freedom (dof) mass-spring system is presented. In deriving the algorithms, the governing differential equations are solved to come up with two schemes separately suitable for viscous and dry-friction damping estimations. Numerical study of a combined-damping system demonstrates a perfect match between the estimated values and the simulation parameters. The method is also applied to an experimental system. Experimental estimates obtained from the proposed method are compared to those obtained using other identification schemes to illustrate the effectiveness and reliability of the new method.
Friction Models and Friction Compensation
1998, European Journal of Control
This paper reviews friction phenomena and friction models of interest for automatic control. Particular emphasis is given to two recently developed dynamic friction models: the Bliman-Sorine model and the LuGre model. These models capture many frictional phenomena observed in laboratory experiments. The behaviours of the models in different situations are discussed in detail. Methods for friction compensation are presented and illustrated with results from practical experiments.
