Investigation and Animation of Spring Dynamic Absorber

Animations of complex mechanical systems with repetitive movements of interest in terms of activation of imagination in their study and research. Action of the spring dynamic absorber, investigation of the physical quantities of proposed mathematical model was implementated using non-linear Runge-Kutta type methods. Two kinds of methods: a nested method of relative accuracy 3(2) and two-sided method with accuracy 2 are consruted in proposed paper. Also estimation of main term of local error are obtained. For all these algorithms, in contrast to other algorithms, only three calls to the right-hand side of the differential equation are required.
