Abstract

The performance of a piezoelectric actuator for active noise cancellation depends primarily on the quality of the actuator material and its design approach, i.e., single-layer or multi-layer actuators, stacks, benders, or amplified actuators. In this paper, material selection and multiphysics modeling were performed to develop an optimal piezoelectric plate actuator for active noise cancellation. The material selection process was analyzed using two multi-criteria decision making (MCDM) approaches for material selection, i.e., figure of merit (FOM) for actuators and the technique for order of performance by similarity to ideal solution (TOPSIS). Of the 12 state-of-the-art piezoelectric actuator materials considered in this article, PMN–28% PT is the best material according to TOPSIS analysis, while PbIn12Nb12O324%−PbMg13Nb13O3−PbTiO3 (PIN24%-PMN-PT) is the best material according to FOM analysis. The ranking of state-of-the-art piezoelectric material categories for actuators according to the two analysis is consistent and the category of monocrystalline piezoelectric materials has the highest actuation performance. The multiphysics modeling was performed using ANSYS Mechanical using two different approaches: one using Ansys Parametric Design Language (APDL) command fragments, the other installing the PiezoAndMEMS ACT extension in ANSYS. Static structure, modal, and harmonic response analyses were performed to determine an optimal pair of piezoelectric plates to be used as an actuator for active noise cancellation. A pair of plates of the same materials, but of different dimensions turns out to be the optimal piezoelectric plate actuator for active noise reduction, according to the two multiphysics modeling methods.

Highlights

  • The negative effects of vibration in machine tools, civil infrastructures, automotive, and aerospace are huge and enormous

  • Potential candidate or alternative state-of-the-art piezoelectric materials for the material selection analysis were selected from each piezoelectric material category discussed in the material section on the basis of their performance for actuator applications, i.e., based on their d33 values

  • This article addressed the daunting task of material selection for piezoelectric plate actuators after a deep review of state-of-the-art piezoelectric materials

Summary

Introduction

The negative effects of vibration in machine tools, civil infrastructures, automotive, and aerospace are huge and enormous. In the machine tool industry, mechanical vibration reduces both production rate and end-product quality, and shortens the service life of machine components, as assessed by [1,2]. The main function of the actuators in active vibration control is to counteract the impact of the disturbance on the structure (mechanical body) by utilizing control signals generated intelligently by the controllers using input signals from sensors that sense the nature and magnitude of the disturbance. This way, the control system can reduce and/or cancel the disturbance by the principle of destructive interference. While there are different types of actuators such as electric, hydraulic, pneumatic, and piezo, to name a few, the only type of actuator focused on in this thesis is the piezoelectric actuator
