Abstract

This paper investigates the sliding adhesive contact mechanics of one-dimensional (1D) hexagonal piezoelectric quasicrystals (PEQCs) coating. Under the assumption of perfect bonding between the coating and the rigid substrate, the frequency response functions for the relevant physical quantities are derived analytically via the double Fourier integral transforms by combining the fundamental solutions of 1D hexagonal PEQCs half-space with the adhesive contact boundary conditions. The adhesion-driven conjugate gradient method (AD-CGM) and the discrete convolution-fast Fourier transform (DC-FFT) technique are employed to numerically calculate the stress and displacement fields. Numerical results reveal the significant effects of the friction coefficient, total charge, adhesion parameters, and coating thickness on the adhesive contact behavior. The findings establish a theoretical foundation for the reliability design and performance optimization of novel PEQCs functional coating in micro-electromechanical systems (MEMS) and nanodevices, particularly with regard to interfacial stress regulation and anti-adhesion surface engineering.

基于DC-FFT的压电准晶涂层滑动黏着接触分析

研究了一维六边形压电准晶体（PEQCs）涂层的滑动粘结接触力学。在涂层与刚性基体完美结合的假设下，结合一维六边形PEQCs半空间基本解与粘接接触边界条件，通过二重傅立叶积分变换，解析导出了相关物理量的频响应函数。采用黏附驱动共轭梯度法（AD-CGM）和离散卷积快速傅立叶变换（DC-FFT）技术对应力和位移场进行了数值计算。结果表明，摩擦系数、总电荷量、粘附参数和涂层厚度对黏着接触行为有显著影响。研究结果为微机电系统（MEMS）和纳米器件中新型peqc功能涂层的可靠性设计和性能优化奠定了理论基础，特别是在界面应力调节和抗粘附表面工程方面。

期刊介绍： Archive of Applied Mechanics serves as a platform to communicate original research of scholarly value in all branches of theoretical and applied mechanics, i.e., in solid and fluid mechanics, dynamics and vibrations. It focuses on continuum mechanics in general, structural mechanics, biomechanics, micro- and nano-mechanics as well as hydrodynamics. In particular, the following topics are emphasised: thermodynamics of materials, material modeling, multi-physics, mechanical properties of materials, homogenisation, phase transitions, fracture and damage mechanics, vibration, wave propagation experimental mechanics as well as machine learning techniques in the context of applied mechanics.
