Journal ArticleDOI
Application of wavelet energy and Shannon entropy for feature extraction in gearbox fault detection under varying speed conditions
TL;DR: For fault diagnosis of gearbox in the run-up condition, primarily the obtained vibration signals from an acceleration sensor of automotive gearbox test setup are sampled at constant time increment by an acquisition card and the Morlet wavelet is used.
Journal ArticleDOI
A numerical study of free and forced vibration of composite sandwich beam with viscoelastic core
TL;DR: In this paper, a finite element code is developed for structural response analysis of the free and forced vibration of a sandwich beam with composite faces and viscoelastic core, where independent transverse displacements on two faces and linear variations through the depth of the beam core are considered.
Journal ArticleDOI
Three-dimensional free vibration of variable thickness thick circular and annular isotropic and functionally graded plates on Pasternak foundation
TL;DR: In this paper, a study of three-dimensional free vibration analysis of thick circular and annular isotropic and functionally graded (FG) plates with variable thickness along the radial direction, resting on Pasternak foundation is described.
Journal ArticleDOI
Nonlinear vibration control of functionally graded plate with piezoelectric layers in thermal environment
Vahid Fakhari,Abdolreza Ohadi +1 more
TL;DR: In this paper, the von Karman nonlinear strain-displacement relationship is used to account for the large deflection of the plate, and two control algorithms are employed: classical displacement-velocity feedback control and robust H2 control.
Journal ArticleDOI
Nonlinear free and forced vibration behavior of functionally graded plate with piezoelectric layers in thermal environment
TL;DR: In this paper, a finite element formulation based on higher order shear deformation plate theory is developed to analyze nonlinear natural frequencies, time and frequency responses of functionally graded plate with surface-bonded piezoelectric layers under thermal, electrical and mechanical loads.
