Grinding process monitoring based on electromechanical impedance measurements
(Iop Publishing Ltd, 2015-04-01)
Grinding is considered one of the last processes in precision parts manufacturing, which makes it indispensable to have a reliable monitoring system to evaluate workpiece surface integrity. This paper proposes the use of ...
Synthesis of Viscoelastic Behavior Through Electromechanical Coupling
(2020-01-01)
Background: Viscoelasticity is a property of materials that present elastic and viscous behavior when they experience deformation. The simplest model that can represent the viscoelastic behavior is generally called the ...
Reduction of torsional vibrations excited by electromechanical interactions in more electric systems
(IEEE-Inst Electrical Electronics Engineers, 2021)
This paper studies the excitation of torsional vibrations by electromechanical interaction after the connection of electrical loads. Electrical generation and power system in aircraft are becoming of key importance, ...
Effective Electromechanical Coupling Coefficients of Piezoelectric Adaptive Structures: Critical Evaluation and Optimization
(TAYLOR & FRANCIS INC, 2009)
This work presents a critical analysis of methodologies to evaluate the effective (or generalized) electromechanical coupling coefficient (EMCC) for structures with piezoelectric elements. First, a review of several existing ...
Escape in a nonideal electro-mechanical system
(2002-11-01)
In this work a particular system is investigated consisting of a pendalum whose point of support is vibrated along a horizontal guide by a two bar linkage driven from a DC motor, considered as a limited power source. This ...
