A note on the effect of surface contamination in water wave damping [PDF]
, 2000 Asymptotic formulas are derived for the effect of contamination on surface wave damping in a brimful circular cylinder; viscosity is assumed to be small and contamination is modelled through Marangoni elasticity with insoluble surfactant. It is seen that

Non-linearity in experimental journal bearing dynamics - a new approach [PDF]
, 2009 This article considers the effects of non-linearity in the dynamic properties of a journal bearing and presents a method of constructing the calculations needed in the identification of a non-linear dynamic model of the oil film.

A study of joint damping in metal plates [PDF]
, 2009 For satellite applications the determination of the correct dynamic behaviour and in particular the structural damping is important to assess the vibration environment for the spacecraft subsystems and ultimately their capability to withstand the launch ...

Influence of Spiral Angle on the Performance of Spiral Oil Wedge Sleeve Bearing
International Journal of Rotating Machinery, 2018 Spiral angel is an important structure parameter of spiral oil wedge sleeve bearing, which produces greater impact on bearing performance. Based on JFO boundary condition, the generalized Reynolds equations considering four slip conditions are ...

Effects of Damping and Reynolds Number on Vortex-Induced Vibrations [PDF]
, 2007 Vortex-induced vibrations have been studied experimentally with emphasis on damping and Reynolds number effects. Our system was an elastically-mounted rigid circular cylinder, free to oscillate only transverse to the flow direction, with very low ...

Improved VSG strategy of grid-forming inverters for supporting inertia and damping
Frontiers in Energy ResearchA virtual synchronous generator (VSG) strategy can introduce the rotational inertia and damping characteristics of the synchronous generator to the static inverter, e.g., PV, wind generation, and ESS, which are used to enhance the system frequency ...

An analog circuit experiment on vibrational resonance of an underdamped bistable system
The Journal of Engineering, 2022 The underdamped vibrational resonance of a bistable analogue circuit is investigated. For a wide range of damping coefficients, vibrational resonance phenomena are more robust than over‐damped states. In particular, the vibration resonance curve reenters
