Influence of nonlinear effects on the acoustic levitation of small spheres
(IEEEChicago, Illinois, 2014-09-03)
This paper presents the nonlinear characterization of a single-axis acoustic levitator and the analysis of the influence of nonlinear effects on the acoustic levitation of small spheres. First, the nonlinear characterization ...
Energy method to calculate the density of liquids using ultrasonic reflection techniques
(2001-12-01)
In this work it is introduced a new approach to calculate the density of liquids in terms of the energies of the acoustic signals. This method is compared to other methods in the time domain (peak-to-peak amplitudes) and ...
Anfis applied to the prediction of surface roughness in grinding of advanced ceramics
(2011-12-01)
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 ...
Acoustic image-based damage identification of oxide aluminum grinding wheel during the dressing operation
(2019-01-01)
Grinding is a finish process of parts that require high precision and tight dimensional tolerance, which owe high value-added. As the grinding process takes place, the cutting surface of the grinding wheel undergoes wear ...
Calcium modified lead titanate/poly-ether-ether-ketone composite for acoustic emission sensors
(2005-12-01)
Composites made of calcium modified lead titanate ceramic powder and poly (ether-ether-ketone) high performance polymer matrix were prepared in the film form using a hot press. The acoustic and electromechanical properties ...
Study on the effect of the temperature in acoustic emission sensor by the pencil lead break test
(2019-01-25)
The Pencil Lead Break (PLB) method is used to reproduce an artificial source of acoustic emission. This method consists of breaking a pencil lead which has its size and thickness determined carefully in a certain angle in ...
Study on the effect of the temperature in Acoustic Emission Sensor by the Pencil Lead Break Test
(Ieee, 2018-01-01)
The Pencil Lead Break (PLB) method is used to reproduce an artificial source of acoustic emission. This method consists of breaking a pencil lead which has its size and thickness determined carefully in a certain angle in ...
PTCa/PEEK composite acoustic emission sensors
(2006-10-01)
Composites made of Calcium-modified lead titanate (PTCa) and poly (ether-etherketone) (PEEK) high performance polymer matrix were prepared in the film form using a hot press. The ceramic volume fraction reaches up to 60 ...
Neural networks models for wear patterns recognition of single-point dresser
(2013-09-24)
Grinding is a workpiece finishing process for advanced products and surfaces. However, the constant friction between workpiece and grinding wheel causes the latter to lose its sharpness, thereby impairing the result of the ...
