Grinding process monitoring based on electromechanical impedance measurements
(Measurement Science & technology, 2015-04-01) [Artigo]
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 ...
Evaluation of neural models applied to the estimation of tool wear in the grinding of advanced ceramics
(Expert Systems with Applications, 2015) [Artigo]
Grinding wheel wear, which is a very complex phenomenon, causes changes in most of the shapes and properties of the tool during machining, reducing the efficiency of the grinding operation and impairing workpiece quality. ...
Fatigue analysis of dental prostheses by finite element method (FEM)
(ASME International Mechanical Engineering Congress and Exposition, Proceedings (IMECE), 2015-01-01) [Trabalho apresentado em evento]
Introduction and Objectives: The dental prostheses are typical biomechanical structures because they have the objective to restore the mastication functions and are responsible for replacing the original tooth that was ...
Contribution of electrical parameters on the dynamical behaviour of a nonlinear electromagnetic damper
(Nonlinear Dynamics, 2015-02-01) [Artigo]
This study explores the dynamical behaviour of electromechanical systems used as vibration absorber. A nonlinear system is considered, with the nonlinearity coming from Duffing-type stiffness. The mathematical modelling ...
