Analysis of complex modal instability of a minimal friction self-excited vibration system from multiscale fractal surface topography

, 2021
In order to reveal the stability and nonlinear characteristics of the friction self-excited vibration system from the perspective of microscopic multiscale fractal surface topography, a minimal two-degree-of-freedom mathematical model of the disc brake ...

Self-Excited Vibrations in Drillstrings

SPE Annual Technical Conference and Exhibition, 1987
Abstract Vibrations created by drag bits can cause premature failure of drillstring components and fracture cutters. Unfortunately, there has been no theory that adequately explains how drag bits excite drillstrings. Our paper shows that these vibrations are self excited by the interaction of drillstring, bit, and formation. Results show

Experimental investigation on the avoidance of self-excited vibrations

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007
Self-excited vibrations are observed in many technical applications. Frictional contacts are often involved in the mechanism which generates vibrations. Reasons for the excitation mechanisms are decreasing friction characteristics depending on the sliding velocity, fluctuating normal loads or different geometrical effects.

Boiling heat transfer enhancement by self-excited vibration

International Journal of Heat and Mass Transfer, 2020
Various methods have been proposed to improve the boiling heat transfer coefficient. In this study, subcooled pool boiling is performed using a thin brass plate that is partly attached close to a heating surface. The plate can be vibrated because boiling
