The Approximate Analytical Solutions for the Differential Equations which Desccribe Free Vibrations of Non-Linear Mechanical Systems
Cauteș, Gheorghe; Oproescu, Gheorghe (Universitatea "Dunărea de Jos' din Galați, 2006)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. ...
