Influence of system parameters on buckling and frequency analysis of a spinning cantilever cylindrical 3D shell coupled with piezoelectric actuator

Abstract

In this research, buckling and vibrational characteristics of a spinning cylindrical moderately thick shell covered with piezoelectric actuator carrying spring-mass systems are performed. This structure rotates about axial direction and the formulations include the Coriolis and centrifugal effects. In addition, various cases of thermal (uniform, linear, and nonlinear) distributions are studied. The modeled cylindrical moderately thick shell covered with piezoelectric actuator, its equations of motion, and boundary conditions are derived by the Hamilton's principle and based on a moderately cylindrical thick shell theory. For the first time in the present study, attached mass-spring systems has been considered in the rotating cylindrical moderately thick shells covered with piezoelectric actuator. The accuracy of the presented model is verified with previous studies. The novelty of the current study is consideration of the applied voltage, rotation, various temperature distributions, and mass-spring systems implemented on proposed model using moderately cylindrical thick shell theory. Generalized differential quadrature method is examined to discretize the model and to approximate the governing equations. In this study, the simply supported conditions have been applied to edges [Formula: see text] and cantilever (clamped–free) boundary conditions has been studied in x = 0, L, respectively. Finally, the effects of the applied voltage, angular velocity, temperature changes, and spring-mass systems on the critical voltage, critical angular speed, critical temperature, and natural frequency of the structure are investigated.

Frequency characteristics of a viscoelastic graphene nanoplatelet–reinforced composite circular microplate

“…In addition, with the aid of an experimental study, Rafiee et al (2009) reported that the composite structures which are reinforced with GPL are much stronger than the reinforced structures with single walled carbon nanotube, double walled carbon nanotube, and MWCNT. Moreover, a large number of studies (Ebrahimi et al, 2019a(Ebrahimi et al, , 2019b(Ebrahimi et al, , 2019c(Ebrahimi et al, , 2019dEsmailpoor Hajilak et al, 2019;Ghabussi et al, 2019Ghabussi et al, , 2020Habibi et al, 2019aHabibi et al, , 2019bHabibi et al, , 2019cHabibi et al, , 2019dHashemi et al, 2019;Mohammadgholiha et al, 2019;Mohammadi et al, 2019;Pourjabari et al, 2019;Safarpour et al, 2018Safarpour et al, , 2019aSafarpour et al, , 2019bShokrgozar et al, 2019) claimed that adding a little bit of GPL into the epoxy matrix results in a structure that has a remarkable property in thermo-electro-mechanical aspect. In the field of improving the mechanical properties, enhancing the elastoplastic stability and instability of sheet metal is presented in some research works with the aid of experimental and finite element method (Gao et al, 2018a(Gao et al, , 2018b(Gao et al, , 2018c(Gao et al, , 2018d(Gao et al, , 2019.…”

Free vibration analysis of twin piezoelectric inclusions embedded in elastic medium

“…Pietrzakowski 24 conducted vibration analysis of active composite plates with PZT actuator/sensor layers, utilizing Kirchhoff’s and Mindlin’s kinematic assumptions. In Shokrgozar et al, 25 a comprehensive study was conducted to investigate the buckling and vibration characteristics of a spinning cylindrical, moderately thick shell covered with PZT actuators with spring-mass systems. The analysis was performed using Hamilton’s principle and relied on the theory of a moderately thick cylindrical shell.…”

Effect of trapezoidal shapes and non-uniform edge loads on buckling behaviour of plates with cutouts

“…Ali et al. 27 studied the impact of buckling and frequency investigation of a spinning cantilevered cylindric 3D shell conjugated with piezoelectric mechanism. Sushanta Ghuku and Kashinath Saha 28 examined the effect of free vibration on distorted curvilinear beam incorporated with rotary inertia and shear distortion impacts.…”
