چکیده
In this paper, the method of electric analog synthesis is applied to design a piezo-electro-mechanical arch able show capacity multimodal damping. An electric-analog circuit designed by using finite number lumped elements representing equivalent curved beam. Spatial and frequency coherence conditions are proven be verified for modes damped: in fact, lumped-element can damp only vibration modes. Analogous boundary ensured, so that natural frequencies mode shapes both beam equal. The instance considered here mitigation arch. Having view towards prototypical applications, all simulations consider values physically feasible passive circuital elements. It believed present results may represent step multi-physics metamaterials based on micro-structures exploiting principle

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
A New Approach to Piezoelectric Shunt Damping
Piezoelectric transducer (PZT) patches can be attached to structures in order to reduce vibration. The PZT patches essentially convert vibrational mechanical energy to electrical energy. The electrical energy can be dissipated via an electrical impedance. This paper introduces a method of implementing an arbitrary impedance using a current source and digital signal processor (DSP). The \synthet...

Stability analysis of piezoelectric beams
Piezoelectric materials are used in many engineering application. When modeling piezoelectric materials the standard assumption is that the electromagnetic field which is used to actuate the piezoelectric material is quasi static. In this paper we show that although the assumption of a quasi static electrical field is valid when one is interested in simulating a piezoelectric material, this ass...
متن کاملEquivalent electrical network for performance characterization of piezoelectric peristaltic micropump
Utilizing an electronic–hydraulic analogy, this study develops an equivalent electrical network of a piezoelectric peristaltic micropump which has not been modeled the whole system operation completely by computational fluid dynamics (CFD) or equivalent electrical network so far due to its excessive complicated structure. The validity of the proposed model is verified by comparing the simulatio...
