نویسندگان
چکیده
A cubic Bézier-profile plate for multimodal vibration energy harvesting was developed. The design of the based on an optimization procedure in which profile optimized via parameters a Bézier curve to meet requirements. exploited its first bending mode and twisting mode. conversion into electrical by electromagnetic induction with magnet attached corner plate. These two closely spaced modes achieved multi-modal device. Prototypes device were manufactured using numerical-control machining process. experimental results good agreement specifications. With same base lengths, height, thickness, maximum von Mises stress proposed much lower due bell-shaped profile. chosen effective closely-spaced harvester. flexibility controllable parametric curve, high freedom harvester specified frequency ratios could be achieved.

متن کاملA periodic folded piezoelectric beam for efficient vibration energy harvesting
Periodic piezoelectric beams have been used for broadband vibration energy harvesting in recent years. In this paper, a periodic folded piezoelectric beam (PFPB) is introduced. The PFPB has special features that distinguish it from other periodic piezoelectric beams. The Adomian decomposition method (ADM) is used to calculate the first two band gaps andtwelve natural frequencies of the PF...
متن کاملNonlinear energy harvesting through a multimodal electro-mechanical system
A semi-analytical method is used to illustrate the behavior of a multimodal nonlinear electromechanical system which is under base-excitation. System is considered as piezo-ceramic patches attached to a cantilever beam coupled to a resistive load. The cantilever beam is modeled as a nonlinear Timoshenko beam using Assumed Mode method and equations of motion are derived through Lagrange's equati...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Design of triads for probing the direct through space energy transfers in closely spaced assemblies.
Using a selective stepwise Suzuki cross-coupling reaction, two trimers built on three different chromophores were prepared. These trimers exhibit a D(^)A1-A2 structure where the donor D (octa-β-alkyl zinc(II)porphyrin either as diethylhexamethyl, 10a, or tetraethyltetramethyl, 10b, derivatives) through space transfers the S1 energy to two different acceptors, di(4-ethylbenzene) zinc(II)porphyri...
