Calculation of harmonic vibrations of the linear systems by the method of Lagranzh of the second family

О.А. Yurchenko
Annotations languages:

In the article the method of research of the forced vibrations of the mechanical systems is laid out by a vehicle which is based on equalizations of Lagranzha the second family. The discrete systems are considered with the n degrees of liberty under the action of harmonic revolting forces.
Keywords: discrete system, harmonic force, quadratic form
