Vibration of a single-walled carbon nanotube embedded in an elastic medium under a moving internal nanoparticle

Vibration of single-walled carbon nanotube embedded in an elastic medium under excitation of a moving nanoparticle is analyzed in this paper. Based on the Winkler spring model and the Euler-Bernoulli beam model, the time-domain responses of the single-walled carbon nanotube subjected to the moving transverse load with three different boundary conditions are computed by using the Newmark method. The effects of velocity and the excitation frequency of the moving internal nanoparticle and boundary conditions on the dynamic deflections of the single-walled carbon nanotube are discussed.
