Questions, related to determination of optimum number of degrees of liberty of the discrete mechanical systems which make basis of construction of rational calculation mathematical models, are considered in the article. The article is devoted development of the methods of construction of discrete models of the oscillating mechanical systems and methods of their research considered before by differential equalizations which in an aggregate with the initial conditions of motion make basis of mathematical model of the mechanical system.
