  1. NONLINEAR DYNAMICS OF CABLE GALLOPING VIA A TWO-DEGREE-OF-FREEDOM NONLINEAR OSCILLATOR

    YU, BO

    The galloping vibrations of a single transmission cable that may vibrate transversely and torsionally has been investigated via a two-degree-of-freedom oscillator. The analytical solutions of periodic motions for this two-degree-of-freedom system are represented by the finite Fourier series. The …

  2. Movimentos induzidos por vórtices (VIM) de plataformas TLWP submetidas a correntes de alta intensidade

    Lamas, Francisco de Mello Leal SantiagoUniversidade Federal do Rio de Janeiro2017

    Vortex Induced Motions (VIM) classified as galloping occurs frequently in TLWP Platforms, however these movements are not always correctly taken into account during design phases. This work aimed to develop a formulation that represent this kind of movement for sway and yaw degrees-of-freedom. …

We also examine quasi-static modes of propulsion in which the insect's legs are kept stationary: specifically, Marangoni propulsion and meniscus-climbing. Special attention is given to rationalizing the propulsion mechanisms …

  11. Characterization of gait energetics for electrically actuated quadrupeds

    Evans, Kathryn Louise, S.M. Massachusetts Institute of TechnologyMassachusetts Institute of Technology2016

    … Analysis of trotting, pronking, bounding and galloping gaits reveals trotting to be the most energetically efficient gait across Froude numbers from 0.2 to 45. This trend represents a significant difference from animals, which transition to a gallop at a Froude number between 2 to 3.
