摘 要:This paper deals with the study of the temperature effect on the nonlinear vibration behavior of nanoplate-based nano electromechanical systems(NEMS) subjected to hydrostatic and electrostatic actuations. Using Eringen's nonlocal elasticity and Gurtin–Murdoch theory, the nonlocal plate model is derived through Hamilton's principle. The governing equation which is extremely nonlinear due to the geometrical nonlinearity and electrostatic attraction forces is solved numerically using the differential quadrature method(DQM). The accuracy of the present method is veriied by comparing the obtained results with the experimental data and those in the literature and very good agreement is obtained. Finally a comprehensive study is carried out to determine the inluence of temperature on the nonlinear vibration characteristics of NEMS made of two different materials including aluminum(Al)and silicon(Si) and some conclusions are drawn.
