in this paper, an analytical study of the forced vibrations of hexapod table is studied. considering external force as a time sinusoid force, forced vibrations of the platform are investigated. resonance frequencies and vibrations of the moving platform are also calculated in different directions. the results of the analytical approach are verified using fem simulation. modelling the harmonic m...

Abstract Purpose Dynamic loads like traffic make bridges vibrate. Especially for with a large span, vibrations have significant impact on their structural stability and durability. Due to material defects, fatigue other influences, bridge typically has random irregularities, which affect its dynamic response. In this work, an effective mathematical approach is presented study the response of mo...

Random telegraph noise in the electric current produced by shot noise is predicted for an array of movable colloid particles by Monte Carlo and molecular dynamics calculations. The electron transport is attributed to the shuttle mechanism where moving colloid particles carry charges. The colloid-particle motion induced by the source-drain voltage shows periodic and/or quasiperiodic vibrations, ...

The structure Harmony-Gamma is a metallic assembly representative of an industrial for which the vibratory response influenced by apparition nonlinear phenomena within two specific types joints, first corresponding to friction joints and second elastomer joints. present study extends previous work based on experiments numerical simulations subjected harmonic vibrations [1]. More specifically, v...
