Nonlinear Vibrations of a Beam with a Mass Subjected to Alternating Electromagnetic Force

In this report, the parametric nonlinear forced vibrations of a beam with a mass subjected to alternating electromagnetic force are investigated analytically and experimentally. The beam is fixed at one end, and an alternating electromagnetic force acts on the mass attached to the other end of the beam. In the analysis, the governing partial differential equations are solved by harmonic balance method, and the second order superharmonic and the one-second order subharmonic vibrations are carried out by the Newton Rapson method, and are compared with the experimental results.
