Severe vibrations such as earthquakes threaten to demolish or cause damage to built structures during their lifetime. Mitigation of such damage can be done by using control devices such as actuators. In this paper, an algorithm is proposed to analyze the nonlinear behavior of a portal frame supported by an actuator. The results were compared with those for a frame without actuator. The algorithm was developed in accordance with the Timoshenko beam element theory. ANSYS verified the results for the cases of a frame supported by a damper element and a frame without actuator. The results support the efficiency of the algorithm in reducing frame vibration and top-node displacement.

“…Under the premise of fulfilling the demand of engineering precision, low order mode is used as the basis vectors to truncate the high order modal for decoupling. 4. In reference to the decoupled equations and the finite element analysis results, the proportional feedback control method and independent modal control method are studied based on LQR (two linear optimal control) and calculate the gain of active structural control to control the vibration of the structure.…”

The application of intelligent material systems and structures is very extensive, which is not only in sophisticated weapons for national defense such as aircraft, ships, but also in various fields of the national economy. They are of great strategic significance especially in the field of high technology. Currently the main materials of intelligent material systems and structures include shape memory materials, piezoelectric materials (including piezoelectric ceramics and piezoelectric polymer), electrostrictive material, optical fiber and the current variant and magnetic current variant, etc. A material system and structure integrating driving, sensing and controlling can be achieved by combining the use of these smart materials' function, with ingenious and exquisite composite design and fabrication. This paper adopts the finite element method that is widely used in engineering to model the plate structure. It analyzes the finite element and implements numerical simulation research on the active vibration control.

“…Harvesting of energy from a piezoelectric structure with the help of impact load includes the interactions of (i) impact load, (ii) piezoelectric patch and (iii) the electrical circuit [10][11]. As the dynamic load generates the charge within layers of piezoelectric consequently, mechanical strain is produced which is further used in rectifying circuit.…”

In this research work, an experimental model is developed to apply the dynamic periodic load on piezoelectric material for energy harvesting. The proposed setup is analyzed to calculate the energy harvested with circular piezo-patch with end supported boundary conditions. Piezo patch is connected with full bridge rectifier circuit under dynamic loading condition to calculate the output of the system. The proposed setup consists of a force sensor, a printed circuit board (P.C.B.) with calibration circuit, a LCD display unit, a stepper motor, a suitable power source and a robust mechanism to apply the dynamic periodic load. The input dynamic load can be varied by varying the height of the piezo-patch. Mathematical modeling of the proposed system has also been developed and successfully validated with experimental results. It is observed that the proposed setup and mathematical modeling accurately apply varying dynamic load and able to calculate the output of the system.
