On Self-Excited Friction Vibrations in Brakes

Volume 3A: 15th Biennial Conference on Mechanical Vibration and Noise — Vibration of Nonlinear, Random, and Time-Varying Systems, 1995
Abstract Dynamic processes in machines resulting from the interaction between rough rubbing surfaces are called self-excited friction vibrations in the theory of vibrations. Such vibrations are generated in machines brakes, causing the instability of then-operation and various noise effects.

Differential evolution for system identification of self-excited vibrations

Journal of Computational Science, 2015
This study uses a differential evolution method to identify the coefficients of second-order differential equations of self-excited vibrations from a time signal. The motivation is found in the frequent occurrence of this vibration type in physics and engineering. In the proposed method, an equation structure is assumed at the level of the differential

Self-Excited Vibrations in Metal Cutting

Journal of Engineering for Industry, 1959
The basic mechanisms which cause self-excited vibrations of a cutting tool relative to the work are discussed in a qualitative manner. Similarly, mechanisms inherent in the cutting process which can damp or limit vibrations are discussed. Experiments are presented which are in agreement with the theory.

Vibration Characteristics of Self-excited Vibration About Sliding Bearings

2020
This paper shows vibration characteristics of a sliding bearings. Especially, we study self-excited vibration (Oil whirl) of the sliding bearings. We tried three analysis methods, which are trajectory of shaft vibration and tracking analysis, and particle number of wear debris in lubricant generated by direct contact between a shaft and outer race of ...

Vibration Absorbers for a Class of Self-Excited Mechanical Systems

Journal of Applied Mechanics, 1993
An averaging methodology is employed in studying dynamics of a two-degree-of-freedom nonlinear oscillator. The main system is modeled as a van der Pol oscillator under harmonic forcing. The objective is to reduce its amplitude of oscillation near resonance, by attaching to it a damped vibration absorber with a Duffing spring.

Quenching of self-excited vibrations: one- and two-frequency vibrations

Journal of Sound and Vibration, 1975
Abstract An analysis is presented of the possibility of initiation of two-frequency self-excited vibrations, and it is shown on this basis, and amply documented by analogue solutions, that the occurrence of such a phenomenon is rather exceptional in the systems being examined.
