摘要

本文采用Gurtin-Murdoch (GM)表面/界面能方法，研究了压电纳米传感器(PENS)在非线性静电激励和谐波力作用下的无量纲固有频率(DNF)和非线性动力学响应(NDR)的表面/界面能对拉入失稳分析的影响。为此，采用Hamilton方法、假设模态和拉格朗日-欧拉理论以及弧长延延法和复平均法研究了拉梅常数、残余应力、压电常数和质量密度等表面/界面参数对拉入不稳定电压分析的影响。

NONLINEAR VIBRATION RESPONSE OF PIEZOELECTRIC NANOSENSOR: INFLUENCES OF SURFACE/INTERFACE EFFECTS

In the present work, surface/interface energy effects for pull-in instability analysis on dimensionless natural frequency (DNF) and nonlinear dynamics response (NDR) of piezoelectric nanosensor (PENS) subjected to nonlinear electrostatic excitation and harmonic force are studied using Gurtin–Murdoch (GM) surface/interface energy approach. To achieve this purpose, the Hamilton’s approach, assumed mode and Lagrange–Euler’s theories and also arc-length continuation and complex averaging methods are used to investigate influences of surface/interface parameters of PENS such as Lame’s constants, residual stress, piezoelectric constants and mass density for analysis of pull-in instability voltage.
