Abstract
We consider a system composed of two masses connected by linear springs One of the masses is in contact with a driving belt moving at a constant velocity Friction force with Coulomb’s characteristics acts between the mass and the belt Moreover the mass is also subjected to a harmonic external force Several periodic orbits including stick phases and slip phases are obtained In particular the existence of periodic orbits including a part where the mass in contact with the belt moves in the same direction at a higher speed than the belt itself is proved Nonsticking orbits are also found for a nonmoving belt We prove that this kind of solution is symmetric in space and in time
