Locomotion based on nonlinear magneto-elastic elements

In this paper we discuss an approximately steady motion of two equal mass points, connected by a non linear magneto-elastic element. It is supposed that the system moves along a straight line in the presence of internal excitation and non symmetric Coulomb dry frictional force acting from the surface upon each mass point opposite to the direction of motion. Thereby, the magnitude of this force is also dependent on the direction of motion. Excitation is carried out due to action internal harmonic forces. Such forces arise for a spring made of a magnetizable elastic material by the influence of an external magnetic field.
