A research of new potential vibration cancellation techniques with the use of piezo stacks

Abstract

Piezoelectric materials offer an ability to exchange energy between electrical and mechanical systems with fair ease, by using the direct and inverse piezoelectric effect. Piezoelectric transceivers, sensors, microphones, actuators or active acoustic noise cancellation devices are some of many applications for piezoelectric materials. Due to the natural ability of the material to convert electricity and mechanical strain, solutions based on piezoelectric materials are often compact and allow applications on micro scales. This article aims at expanding the applicability of piezoelectric materials to dampen vibrations of broader spectrum and bigger amplitudes, in hopes for finding new possible solutions for damping vibrations generated by heavy duty equipment or machines associated with manufacturing processes. The study involves parallel attempts at creating algorithms and mathematical models using classical mathematical algebra and deep learning techniques to actively dampen incoming vibrations with the use of piezoelectric plates. The novelty of this study would involve using piezoelectric plates of different sizes and properties in a single stack, to dampen the frequencies and amplitudes of incoming vibrations.
