The Approximate or Exact Analytical Solutions for the Differential Equations Which Describe Parametric Free Vibrations of Mechanical Systems
Cauteș, Gheorghe (Universitatea "Dunărea de Jos" din Galați, 2013-05-01)The vibrations of many mechanical systems can be described by differential equations that have coefficients that depend on time. It is difficult to determine the approximate or exact analitical solutions of these equations. In ...
