![]() NONLINEAR DYNAMICS OF A FLUID GYROSCOPE
Svetoslav Nikolov, Nataliya Nedkova The article examines the dynamic behavior of a system of three nonlinear Ordinary Differential Equations describing the behavior of a liquid gyroscope. Our analysis and simulations (with specific choice of parameters) demonstrates that the equilibrium states are three – of saddle and saddle-focus type, and the oscillations are conditionally divided into two levels – "macro" and "micro" level. Changing the parameter leads to modification of the period of the oscillations of the "macro" level.
