Title: Friction induced vibrations of a cantilever beam Keywords: Continuous system,FEM,Self-excited vibrationAbstract: In the present work friction induced vibrations of a fixed support beam considered as a continuous system are studied. The dynamic model is made using FEM, as the internal damping is taken into account (Rayleigh damping). The friction force, applied on the beam is nonlinear function of the relative velocity of sliding and it is modeled as a cubic function in it is drop-down section. Stationary process of motion is considered in the study. The problem is solved using Matlab Slim-ulink. The numerical solution is confirmed by experiment.
