On a control design to an AFM microcantilever beam, operating in a tapping-mode, with irregular behavior
(Proceedings of the ASME Design Engineering Technical Conference, 2011-12-01) [Trabalho apresentado em evento]
In last decades, control of nonlinear dynamic systems became an important and interesting problem studied by many authors, what results the appearance of lots of works about this subject in the scientific literature. In ...
On Nonlinear Response of a Non-ideal System with Shape Memory Alloy
(Modeling, Simulation and Control of Nonlinear Engineering Dynamical Systems, 2009-01-01) [Trabalho apresentado em evento]
Determination of minimum fluidization velocity for gas-solid beds by experimental data and numerical simulations
(ASME 2011 International Mechanical Engineering Congress and Exposition, IMECE 2011, 2011-12-01) [Trabalho apresentado em evento]
The purpose of this work is to predict the minimum fluidization velocity Umf in a gas-solid fluidized bed. The study was carried out with an experimental apparatus for sand particles with diameters between 310μm and 590μm, ...
Influence of vegetable oil in the viscosity of biodiesel-a review
(SAE Technical Papers, 2008-12-01) [Trabalho apresentado em evento]
Viscosity is a measure fluid resistance to flowing, affecting the fuel spray in the combustion chamber and, by this way, thus the formation of carbon deposits. The analysis of the influence of vegetable oil viscosity in ...
Fuzzy logic to predict thermal damages of ground parts
(Proceedings of the 10th IASTED International Conference on Artificial Intelligence and Applications, AIA 2010, 2010-07-20) [Trabalho apresentado em evento]
One of the critical problems in implementing an intelligent grinding process is the automatic detection of workpiece surface burn. This work uses fuzzy logic as a tool to classify and predict burn levels in the grinding ...
Anfis applied to the prediction of surface roughness in grinding of advanced ceramics
(Proceedings of the IASTED International Conference on Artificial Intelligence and Soft Computing, ASC 2011, 2011-12-01) [Trabalho apresentado em evento]
This paper introduces a methodology for predicting the surface roughness of advanced ceramics using Adaptive Neuro-Fuzzy Inference System (ANFIS). To this end, a grinding machine was used, equipped with an acoustic emission ...
Advanced ceramics: Evaluation of the mechanism of stock removal and ground surface quality
(SAE Technical Papers, 1999-12-01) [Trabalho apresentado em evento]
The aim of this work is to evaluate the mechanism of stock removal and the ground surface quality of advanced ceramics grounded by a plane tangential grinding process with diamond grinding wheels. The analysis of the ...
Production and heat treatment of cast graphitic steels with additions of niobium
(Proceedings - 15th IFHTSE - International Federation for Heat Treatment and Surface Engineering Congress 2006, 2006-12-01) [Trabalho apresentado em evento]
The optimal combination of the mechanical characteristics of austempered spheroidal graphitic cast steel together with modern casting techniques yielded an economically promising product. The maximum potential of the usage ...
Stick-slip chaos in a non-ideal self-excited system
(Proceedings of the ASME Design Engineering Technical Conference, 2003-12-01) [Trabalho apresentado em evento]
In engineering practical systems the excitation source is generally dependent on the system dynamic structure. In this paper we analyze a self-excited oscillating system due to dry friction which interacts with an energy ...
Finishing of flat parts led by lapping kinematics on abrasive disc dressed in agreement with overlap factors
(ASME International Mechanical Engineering Congress and Exposition, Proceedings, 2009-09-14) [Trabalho apresentado em evento]
This paper discusses the investigation of an abrasive process for finishing flat workpieces, based on the combination of important grinding and lapping characteristics. Instead of loose abrasive grains between the workpiece ...
