Parametric resonances of floating wind turbines blades under vertical wave excitation
MATEC Web of Conferences, 2018 The parametric resonances of the blades in floating offshore wind turbines are theoretically and experimentally investigated. In the theoretical analysis, each blade is pinned to a horizontal, rotating shaft and has a spring with rotational stiffness at ...

Parametric array technique for microbubble excitation
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2011 This study investigates the use of an acoustic parametric array as a means for microbubble excitation. The excitation wave is generated during propagation in a nonlinear medium of two high-frequency carrier waves, whereby the frequency of the excitation wave is the difference frequency of the carrier waves.

Numerical Study of Forced Vibration Suppression by Parametric Anti-Resonance
Archives of Acoustics, 2016 The parametric anti-resonance phenomenon as an active damping tool for suppression of externally excited resonant vibration is numerically studied herein. It is well known fact that the anti-resonance phenomenon, i.e.

Parametric excitation of pipes through fluid flow
Computer Assisted Methods in Engineering and Science, 2023 In this paper the dynamic behaviour of a continuum inextensible pipe containing fluid flow is investigated. The fluid is considered to be incompressible, frictionless and its velocity relative to the pipe has the same but time-periodic magnitude along ...

On the dynamics of a parametrically excited planar tether [PDF]
Communications in Nonlinear Science and Numerical Simulation, 2015 This study is concerned with a planar tether containing payloads in which two lumped masses are fitted whose mutual distance can be contrived to change periodically in time. This periodical variation in distance of the two masses is symmetrical and results in a time-varying coefficient of the kinetic energy, which in turn introduces parametric ...
