Investigation Into the Galloping Characteristics of Multispan Iced Covered Conductors [PDF]
IEEE Access, 2022 A full multispan two-degree-of-freedom (2-DOF) iced covered transmission line model is presented. Taking multispan conductors as the research object, based on the Hamiltonian principle, a nonlinear galloping model of multispan conductors considering the influence of insulator strings is established, and its galloping equation is derived.

Three Characteristics of Cheetah Galloping Improve Running Performance Through Spinal Movement: A Modeling Study [PDF]
Frontiers in Bioengineering and Biotechnology, 2022 Cheetahs are the fastest land animal. Their galloping shows three characteristics: small vertical movement of their center of mass, small whole-body pitching movement, and large spine bending movement. We hypothesize that these characteristics lead to enhanced gait performance in cheetahs, including higher gait speed.
