Modeling and stability analysis for an ultrasonic motor

open access: yesVietnam Journal of Mechanics, 2007
The development of motor models, adequate for motor design and optimization is still behind the technological state of the art. The reason for this lies in the fact that a couple of years ago the main emphasis regarding ultrasonic motors was on finding ...

Multiscale analysis of friction behavior at fretting interfaces

open access: yesFriction, 2020
Friction behavior at fretting interfaces is of fundamental interest in tribology and is important in material applications. However, friction has contact intervals, which can accurately determine the friction characteristics of a material; however, this ...

Vortex-induced vibrations of a long flexible cylinder in shear flow [PDF]

open access: yes, 2010
We investigate the in-line and cross-flow vortex-induced vibrations of a long cylindrical tensioned beam, with length to diameter ratio L/D = 200, placed within a linearly sheared oncoming flow, using three-dimensional direct numerical simulation.

A Novel Aerodynamic Force and Flutter of the High-Aspect-Ratio Cantilever Plate in Subsonic Flow

open access: yesShock and Vibration, 2020
This paper focuses on the derivation of the aerodynamic force for the cantilever plate in subsonic flow. For the first time, a new analytical expression of the quasi-steady aerodynamic force related to the velocity and the deformation for the high-aspect-

Influence of mechanical vibrations on quasi-2D silo discharge of spherical particles

open access: yes, 2020
In this paper, we present a study of the influence of mechanical vibrations on silo discharges of granular matter. We propose a pragmatic understanding of the effects of vibrations on silo discharge using the framework of correlations and empirical laws ...
