Optimal distribution of piezoelectric patches for active vibration reduction of a thick plate using singular value decomposition approach [PDF]

open access: yesScientific Reports, 2021
This paper uses the singular value decomposition approach to find the optimal distribution of a set of piezoelectric actuators and sensors in order to suppress the vibrations of a thick plate.

Orientation modulated piezoelectric patches for active vibration reduction of thick plates using a singular value decomposition-based optimization [PDF]

open access: yesScientific Reports
Active vibration reduction in thick plates remains a significant challenge in structural control. This study proposes a novel method for optimizing the orientation of piezoelectric sensor/actuator pairs to enhance vibration suppression.

Analyzing of thick plates with cutouts using the meshless (EFG) method based on higher order shear deformation theories for solving shear-locking issue [PDF]

open access: yesNumerical Methods in Civil Engineering, 2021
Although the finite element method (FEM) is a well-established method for modelling the thick plates, in some cases FEM encounters some difficulties such as shear locking and decrease in the accuracy of results caused by stress concentration around the ...

Fault Identification of Low-Speed Hub Bearing of Crane Based on MBMD and BP Neural Network

open access: yesShock and Vibration, 2022
As the key bearing part of the crane, the low-speed hub bearing of the crane exists in special working conditions of low-speed and alternating heavy load. It is difficult to extract its fault characteristics accurately by existing analysis methods.

Classification of Transmission Modes through a Narrow Slot in a Thick Conducting Screen [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2022
This paper examines electromagnetic energy transmission through a narrow slot in a thick conducting plate when a plane wave is incident to the slot. The slot in the thick plate creates a waveguide structure.

Finite element simulation on residual stress during immersion quenching and pre-stretching of Al7055 thick plates

open access: yesMaterials Research Express, 2022
During the immersion quenching process, severe temperature changes and significant temperature differences between the core and superficial area can give rise to high residual stresses within the aluminum alloy thick plate to cause subsequent machining ...

Research on parameters optimization of bilateral ring gear blank-holder in thick-plate fine blanking [PDF]

open access: yesFracture and Structural Integrity, 2014
To compensate for the poor quality of thick-plate blanking parts in cross-section, this paper suggests using the optimizing bilateral ring gear holder parameters to increase burnish zone and improve cutting precision.
