Abstract
The sampling sequences of counting of pulse characteristics of quasi-harmonics oscillators are used for transition to discrete time in the equations of the movement of nonlinear oscillatory systems with many degrees of freedom. The finite-difference algorithm of modeling of nonlinear dynamics of oscillators is as a result offered. The differential scheme has the second order of accuracy on discrete time, keeps a form of pulse characteristics of oscillators and is well joined to methods of digital processing of signals. The example of modeling of a nonlinear resonance in two coupled Duffing oscillators is given.
