Sweeping piezoelectric patch vibration absorbers
This paper presents a simulation study concerning the low-mid frequencies control of flexural vibration in a lightly damped thin plate, equipped with five time-varying shunted vibration absorbers. The panel is excited by a rain-on-the-roof broad frequency band stationary disturbance. The absorbers are composed of piezoelectric patches connected to time-varying RL shunt circuits. Continuous, swe...
متن کاملDraft: a Principle of Similarity for Nonlinear Vibration Absorbers
With continual interest in expanding the performance envelope of engineering systems, nonlinear components are increasingly utilized in real-world applications. This causes the failure of wellestablished techniques to mitigate resonant vibrations. In particular, this holds for the linear tuned vibration absorber (LTVA), which requires an accurate tuning of its natural frequency to the resonant ...
متن کاملConcurrent Design of Input Shaping and Vibration Absorbers
Systems that exhibit flexible dynamics are susceptible to vibration caused by changes in the reference command, as well as, from external disturbances. Feedback control is an obvious choice to deal with these vibrations, but in many cases, it is insufficient or difficult to implement. Input shaping has proven beneficial for reducing vibration that is caused by changes in the reference command. ...
متن کاملThe Study and Development of Energy Harvesting Vibration Absorbers
Vibrational energy harvesting seeks to convert ambient energy into electricity when battery replacement or line transmission is infeasible or impracticable. Electromechanical mass-spring harvesters are designed to exhibit a resonance frequency close to the principal vibrational frequency of the main or environmental system; excited near to resonance, the harvesters convert the kinetic or potent...
متن کاملAutomated synthesis of mechanical vibration absorbers using genetic programming
Conceptual innovation in mechanical engineering design has been extremely challenging compared to the wide applications of automated design systems in digital circuits. This paper presents an automated methodology for open-ended synthesis of mechanical vibration absorbers based on genetic programming (GP) and bond graphs (GPBG). It is shown that our automated design system can automatically evo...
