Abstract:

The paper presents a corrected mathematical model of a two-mass isolated system. Dynamic processes of a two-part system with excitation, elastic and dissipative nonlinear forces are obtained through mathematical simulation. Numerical experiments have shown that the oscillation shapes and results obtained by a system reduced to one mass are exactly the same as the oscillation shapes and results of a two-mass system with equal masses, but in the case of different masses they are quite different from each other.

Keywords: oscillation; frequency; multi-systems; resonance; stability.
