Large-span roof structures are sensitive to wind loads, and the values taken by code usually cannot meet design requirements. By conducting scaled rigid model pressure tests on a large-span irregular in Xi'an, coefficients of cantilevered curved under different directions were systematically analyzed. The results show that is mainly subjected negative pressure, with local positive at eaves upper surface north building. Strong suction zones easily formed top south building structural strength...
The theoretical model of a Galfenol cantilever energy harvester is investigated for vibration harvesting. Compared with the numerical solution, analytical solution can better capture intrinsic effects physical parameters on performance harvester. In this work, an electromechanical coupled distributed-parameter established based Hamilton's principle, linear constitutive equations magnetostrictive material, and Faraday's law electromagnetic induction. definitions expressions electric damping...
To improve the performance of energy harvesting from transverse galloping, structural and circuit designs are integrated. Tapered harvesters due to more uniform strain distribution with standard direct current (dc), synchronous charge extraction (SCE), parallel or series synchronized switch on inductor (P-SSHI SSSHI) adopted. An electromechanically coupled distributed parameter model considering exact modal shape tapered beam attached bluff body, is established. The electromechanical...
The cantilever beam was commonly designed with uniform cross-section for the galloping energy harvesters. To improve its performance, two tapered harvesters are proposed in this work. In first design, beam’s thickness is linearly changed constant width. second both and width varied. A generalized fluid–structure–electricity coupled distributed-parameter model established by Hamilton principle Gauss law By means of properties Bessel function modal analysis method, exact analytical shape...
