RISEffect of Electromagnetic Actuation on Contact Loss in a Hertzian Contact Oscillator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of electromagnetic actuation (EMA) on the dynamic of a singlesided Hertzian contact forced oscillator is studied near primary and secondary resonances. Emphasis is put on the case where two symmetric EMAs are ...
Galloping of a Wind Excited Tower Under Internal Parametric Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of harmonic internal parametric damping (IPD) on the amplitude and the onset of the periodic galloping of a tower is investigated in the presence of steady and unsteady wind. The structure is modeled by a lumped ...
