摘要

The study of sliding adhesive contact problem can reveal the mechanisms of interface friction, energy dissipation, and electric force coupling, and solve the problem of device performance degradation caused by contact failure. Based on the three-dimensional (3D) general solution of one-dimensional (1D) hexagonal piezoelectric quasicrystals (PEQCs), the sliding adhesion contact problem of 1D hexagonal PEQCs under a 1D hexagonal PEQCs spherical indenter was studied. The frequency response function of 1D hexagonal PEQCs half-space was analytically deduced and transformed into the corresponding influence coefficient. The numerical solution method composed of adhesion-driven conjugate gradient method (AD-CGM) and discrete convolution-Fourier transform (DC-FFT) is used to calculate phonon and phason displacements and stresses, potential and electric displacement. Numerical analysis provides insights into the effects of the friction coefficient, the total charge and adhesion parameters on the adhesion contact of 1D hexagonal PEQCs on half-space. The research results indicate that the influence of adhesion on surface stress and phason displacement is more pronounced, and the influence on other physical quantities can be ignored. The research results obtained here contribute to the optimization of interface design for quasicrystal materials and the improvement of device reliability.
