“…These various controllers can be applied to any structure to reduce undesired vibration. For example, for vibration reduction of conical shells there are many related articles in which piezoelectric patches with different distributions used [15][16][17][18][19][20].…”

“…From the mechanical point of view, most of the articles in this regard [ 1 , 4 , 8 , 9 ] are based on the study of the free vibration of conical shells, to act on the natural oscillation modes under different displacement constraints. However, it should be noted that Li et al [ 10 ] analytically studied the forced vibrations of conical shells, obtaining the equations of motion under different external dynamic loads.…”

“…Jamshidi and Jafari develop several works [ 5 , 8 , 9 , 12 ] on the subject of using piezoelectric actuators and sensors in conical shells for vibration control. In particular, [ 8 , 9 ] focused on designing the distribution of these piezoelectric elements through analytical relations based on the Kirchhoff–Love thin plate theory. Different patch distributions are applied in an ordered manner in longitudinal, circumferential or diagonal directions.…”

Conical shell structures are frequently submitted to severe static and dynamic mechanical loads that can result in situations that affect the service of the systems that are part of, or even cause catastrophic failures. For this reason, a common solution is to design an active deformation control system, usually using piezoelectric patches strategically distributed along the surface of the shell structure. Moreover, these elements may be part of an energy recovery system. This paper details the methodology to topologically optimize the placement of piezoelectric elements through a characteristic function, analysing static and free vibration loading cases by means of the finite element method. Then, the optimal arrangement of the electrode with different polarization profiles is distributed throughout the entire structure. The nature of the loading cases studied corresponds to a general situation where static loads and dynamics vibration are considered. The objective function of the problem only depends linearly on the displacement fields, and therefore, the optimal electrode profile can be obtained for any combination of loads. As a consequence, this technique allows for maximising the electric charge obtained, which results in a greater capacity for monitoring, actuation and/or energy harvesting.

“…In all of the mentioned studies, the effect of piezoelectric layer distribution on the conical shell surface was not discussed. For this purpose, Jamshidi and Jafari (2018a, 2019) evaluated piezoelectric sensor/actuator layer distribution on the conical shell surface with simply supported boundary conditions. The most effective piezoelectric layer distribution on the conical shell surface was determined.…”

In this study, nonlinear vibration of a conical shell with a piezoelectric sensor patch and a piezoelectric actuator patch is evaluated. The strain displacement relation is considered to be nonlinear and based on that the equations of motion and piezoelectric sensor output signal are extracted. For the first time, nonlinear electromechanical equations of motion for the conical shell with a piezoelectric sensor layer and a piezoelectric actuator layer are extracted in detail and presented. The producer of extraction of conical shell electromechanical equations of motions is presented for further clarifications. The output signal of the piezoelectric sensor patch considering the nonlinear strain displacement equation of motion is derived. For controlling the vibration actively, a proportional controller is defined by which the applied actuator signal is determined. The nonlinear electromechanical equations of motion are expanded based on conical shell strains. By applying the Galerkin method, the nonlinear time-domain equations are extracted. The complicated attained equations are solved using the harmonic balance method. Conical shell nonlinear frequency response in uncontrolled condition and controlled condition is computed and compared with each other. The frequency response shows that the active vibration control of the conical shell increases the nonlinearity of the system and reduces the vibration amplitude. In addition, free nonlinear vibration of the proposed system is calculated and presented. The results show higher impacts of piezoelectric patches on the conical shell free vibration response and they can reduce the vibration amplitude dramatically.
