An Object-oriented Application for Analyzing Nonlinear Dynamic Systems with Hysteretic Behavior

The article presents the structure, interface and functionality of an object-oriented educational application for modeling and analysis of 1D nonlinear dynamic systems with hysteresis: oscillators with Dahl, Lu Gre friction elements, and with a rubber-metal shock absorber. Using the application, it is possible to study free and forced oscillations of nonlinear systems under kinematic disturbances. The nonlinear differential equations are solved by the Runge-Kutta and Adams-Bashfort methods. The modular structure of the object-oriented application makes it easy to expand the collections of nonlinear models and numerical methods for solving nonlinear differential equations.
