英文摘要	Based on surface elasticity, the surface effects on the dynamic behavior of a simply supported Euler-Bernoulli nanobeam subjected to a moving oscillator are studied in this paper. The governing equations of motion for the dynamic response of the nanobeam including surface stress effects are derived by using Hamilton's principle. By employing Petrov-Galerkin method, the fourth-order partial differential equations of motion have been reduced to a second-order ordinary differential equations. The resulting equations are solved using Runge-Kutta numerical scheme. The effects of surface stress and velocity of the moving oscillator on the dynamic responses of the nanobeam are discussed in detail. The results indicate that surface stress plays a significant role on the dynamic response of nanobeam.
