To improve the performance and efficiency of ordinary galloping energy harvesters (GEHs), this paper proposes a GEH with striped bluff body. The fluid-structure coupling simulation body oscillator harvester was carried out using COMSOL Multiphysics. cloud diagram in flow field, tip displacement at beam, lifting dragging force, trace frequency response are analyzed. Simulation results show that ...

Abstract The low power and narrow speed range remain bottlenecks that constrain the application of small-scale wind energy harvesting. This paper proposes a simple, low-cost, reliable method to address these critical issues. A galloping harvester with cooperative mode vibration collision (GEH-VC) is presented. pair curved boundaries attached functional materials are introduced, which not only i...

Principal strains were recorded in vivo from the radial and tibial midshafts of three goats as they increased speed and changed gait. These data were compared with strain data measured for the radius and tibia of the dog (Rubin & Lanyon, 1982) and the horse (Biewener, Thomason & Lanyon, 1983b) in order to test the hypothesis that similar peak bone strains (stresses) occur at functionally equiva...

Despite enormous rates of minute ventilation (Ve) in the galloping Thoroughbred (TB) horse, the energetic demands of exercise conspire to raise arterial Pco(2) (i.e., induce hypercapnia). If locomotory-respiratory coupling (LRC) is an obligatory facilitator of high Ve in the horse such as those found during galloping (Bramble and Carrier. Science 219: 251-256, 1983), Ve should drop precipitousl...
