In order to study the galloping mechanism of ice-covered four-split transmission lines in oblique flows, aerodynamic forces and aero-elastic response characteristics crescent-shaped are investigated through wind tunnel tests on rigid models. According Den Hartog Nigel’s theories, damping coefficients calculated based experimental data. The results show that usually suffer from torsional gallopi...

Solar power installations are increasing every year due to the decarbonization policy established around world. Photovoltaic (PV) systems and specifically one-axis solar trackers most used type of in plants. Those slender structures installed open-air areas sometimes subjected high speed winds. During last years, failures these starting appear, them related a dynamic phenomenon called torsional...

In modeling running gaits of biological and robotic quadrupeds, leg mass is often neglected. Analysis of the system angular momentum in a biological model and a robot model indicates that including leg mass is significant in capturing the roll motion in trotting and pacing. Leg mass has a more significant effect on the pitch motion in bounding and is most critical in accurately capturing the dy...
