The Approximate Analytical Solutions for the Differential Equations which Desccribe Free Vibrations of Non-Linear Mechanical Systems

Abstract

The oscillation movement of a mechanical non-linear system is not easy to solve exactly on analytical way. The approximate solutions are based on different methods and give different values with different approximation degree. Our method, based on ”low parameter method” gives an another way for this almost known method and it is applicable at non-linear mechanical systems on free movement.
